Bumbo is a passive item added in The Binding of Isaac: Afterbirth.

Effect[edit | edit source]

• Spawns a familiar which follows Isaac and picks up any nearby coins. Bumbo changes level based on the amount of coins it's collected.

Level 1 (0-5 coins): Bumbo just collects coins to level up.

Level 2 (6-11 coins): Bumbo occasionally drops a pickup, trinket or chest after a room clear.

Level 3 (12-23 coins): Bumbo now fires tears that deal 3.5 damage in the same direction Isaac does. Bumbo's tears have a chance to drop a coin if they hit an enemy.

Level 4 (24+ coins): Bumbo no longer fires tears and instead chases enemies slowly and deals contact damage (2.5 per tick, or 37.5 per second). Bumbo will occasionally drop bombs while chasing enemies or coins.

• After reaching level 4, Bumbo will continue to collect coins, and can drop a pickup, trinket, or chest for each coin it collects, similar to . However, unlike Bum Friend, Bumbo can also drop pedestal items.

Notes[edit | edit source]

• Level 1-3 Bumbo can fly over pits and obstacles, despite having limbs at level 2 and 3 that serve him as legs.
• If Bumbo consumes an absurd amount of coins while level four, Bumbo can become level one again [Unsure if bug]
• If Level 4 Bumbo targets Mega Satan's head, Bumbo will attempt to 'chase' him the entire fight by standing in the middle of the room.
• Level 4 Bumbo's bombs are unaffected by Isaac's bomb synergies.
• Bumbo cannot pick up Sticky Nickels and will hover over them. Level 4 Bumbo can eventually bomb the Sticky Nickel to unstick to the floor.
• Bumbo will pick up Lucky Pennies, without additional benefit to evolution or drops.
• If Bumbo drops a pedestal item, it will be pulled from a random item pool.
• Bumbo will not evolve if he takes coins from exploding the Donation Machine.
• In a RERUN, Bumbo's level is reset.
• Going after resets Bumbo's level[Unsure if bug]. This is likely a side effect of however the game handles the process of adding and removing items during the event, with the most probable reason being that Bumbo’s level simply isn’t stored.

Synergies[edit | edit source]

• : Doubles both the contact and shot damage, when applicable.

Interactions[edit | edit source]

• : Will spawn a level 1 Bumbo regardless of the original Bumbo's current level.
• : The bum friend will follow Bumbo instead of Isaac.
• : Not recommended, as the coins Bumbo collects could have been used to heal Keeper.
• : Due to the large influx of coins spawned, it's technically possible to sustain Bumbo while also maintaining a good level of wealth and health.

In-game Footage[edit | edit source]

Trivia[edit | edit source]

• Bumbo is the main character of his own game, The Legend of Bum-Bo, designed by Edmund McMillen.
• The name is a play on the word bum and Rambo.
• Bumbo Level 1 looks similar to Bum Friend's head.
• According to Edmund, any version of bum that fights is a bumbo.

Coin grading^[1] is the process of determining the grade or condition of a coin, one of the key factors in determining its value. A coin's grade is generally determined by five criteria: strike, preservation, luster, color, and attractiveness. Several grading systems have been developed. Certification services professionally grade coins for tiered fees.

Overview[edit]

A 'grade' measures a coin's appearance. There are generally five main components which determine a coin's grade: strike, surface preservation, luster, coloration and eye appeal. Grading is subjective and even experts can disagree about the grade of a given coin.^[2][1]

History[edit]

U.S. coin grading has evolved over the years to a system of finer and finer grade distinctions. Originally, there were only two grades, new and used. This changed to the letter grading system beginning with the lowest grade – Basal State (also Poor (PO)), then continuing Fair (Fr), About or Almost Good (AG), Good (G), Very Good (VG), Fine (F), Very Fine (VF), Extremely Fine (EF), Almost or About Uncirculated (AU), Uncirculated (Unc) and up to Brilliant Uncirculated (BU). Gem Uncirculated was roughly equivalent in usage to BU at that time. Numerical grades from 1 to 70 now accompany the verbal grades.^[3][4][5][6]

Systems[edit]

Early grading systems[edit]

Con Level 3 Certification

The quality of all coins is not equal and collectors felt the necessity of defining the quality of the coins in order to assess their value. Rim damage, nicks, polishing, cleaning, scratches and other forms of wear are considered factors in grading a coin. Whether or not a coin shows evidence of having been mounted in jewelry also affects its grade.

In the early years of coin collecting, three general terms were used to grade coins:

• good - when circulation had worn the surface of the coin, but major details were still visible.
• fine - when features were less worn and a bit of mint luster showed on the surface. Most major and minor detail visible
• uncirculated - when the features of the coin were sharp and the luster approaching the state of a new coin at the mint.^[7]

Sheldon grading system[edit]

As the collector market for coins grew rapidly in the late 19th and early 20th centuries, it became apparent that a more precise grading standard was needed. Some coins were simply more fine than others, and some uncirculated coins showed more luster and far fewer marks than others. Terms like 'gem uncirculated' and 'very fine' began to see use, as more precise grading descriptions allowed for more precise pricing for the booming collector market.

In 1948, well-known numismatist Dr. William Herbert Sheldon attempted to standardize coin grading by proposing what is now known as the Sheldon Scale, as is detailed below. Sheldon's 1 to 70 grading scale^[clarify], included in his book Penny Whimsy, was originally devised for U.S. large cents but it is now applied to all series.^[8]

European grading system[edit]

European countries use various, roughly equivalent, grading systems. The main features of their systems are presented in the following table:^[9]

American Numismatic Association scale[edit]

As the hobby of numismatics evolved, the need arose for a more concrete grading system. In 1978, the American Numismatic Association published the Official A.N.A. Grading System for United States Coins.^[10] It established grading tiers of, in descending order of preservation, Mint State, About Uncirculated, Extremely Fine, Very Fine, Fine, Very Good, Good and About Good. Most numismatists, as well as third-party grading services, also use two other descriptors for the lowest grades, Fair and Poor. The higher tiers on this scale each encompass two or more 'sub-grades' denoted by the appending of the corresponding Sheldon scale number, such as Very Fine-20 or Very Fine-30. This allows for the recognition of coins which exceed the standard for a given tier, but do not meet the criteria for the next. Grades are commonly abbreviated, and not all numismatists use the numerical grades, so a grade of Fine-12 may be rendered as Fine, F-12, 12 or simply F.^[10]

Certification services[edit]

Coin certification services emerged in the 1980s as a response to the need for buyers and sellers to agree on grading.^[11] For tiered fees, certification services grade, authenticate, attribute, and encapsulate coins in clear, plastic holders.^[12][13]Professional Coin Grading service (PCGS), Numismatic Guaranty Corporation (NGC), Independent Coin Graders (ICG), and American Numismatic Association Certification Service (ANACS) are the most popular services, according to experts. These are the only services whose coins have a special section on eBay, the largest rare coin marketplace. All four firms guarantee the grades and authenticity of their certified coins. Together they have certified over 80 million coins.^[3][4][5][6]

At each of the four main grading companies, a similar process is used. Each coin is graded (on a verbal and 1 to 70 numerical scale) and authenticated by two or more graders, and then assigned a final grade by a finalizer, based in part upon the recommendations of the prior graders. Depending on the company, various descriptors may be added, such as Full Bands for Mercury dimes, Full Bell Lines (FBL) for Franklin Half Dollars, or Deep Mirror Prooflike (DMPL) for Morgan dollars, and the coin's die variety may be noted. The coin is then slabbed and returned to the customer.^[3][4][5][6] In 2010, PCGS and NGC introduced 'Plus' grading for high-end coins graded XF45 to MS68. A plus symbol (+) is added after the grade.^[14][15]

In 2007, the Professional Numismatists Guild (PNG), a US association of rare coin dealers, released the results of a survey of major coin dealers who gave their professional opinions about 11 certification services. PCGS and NGC were rated 'Superior' overall, with ANACS and ICG deemed 'Good'. PCI and SEGS were listed as 'Poor', while called 'Unacceptable' were Accugrade (ACG), Numistrust Corporation (NTC), Hallmark Coin Grading Service (HCGS), American Coin Club Grading Service (ACCGS), and Star Grading Services (SGS).^[16][3][4]

Counterfeit NGC and PCGS holders have been reported, but significant measures have been taken by both services to remedy the problem, such as NGC's use of photographic verification for every coin certified and both services' employment of serial number verification and anti-counterfeiting features in their holders.^{[17][18][3][4]}
