Division IV: Official Mint Modifications
error coinsBy Alan Herbert
March 23, 2010
error coins


Several mint produced varieties occur after the coin has been struck, resulting in the addition of the fourth division to my PDS System. Since most of these coins are either unique or are special varieties, each one must be taken on a case by case basis. All classes listed here are by definition intentional.


I have not listed values as the coins falling in these classes which are sold through regular numismatic channels, are cataloged with the regular issues or are covered in specialized catalogs in their particular area.

 


Matte proofs (IV-A)


Matte proofs as a section include several of the forms of proof coins which have the striking characteristics of a mirror proof but have been treated AFTER striking to give them a grainy, non-refl ective surface.


IV-A-1 Matte Proof (I), Rarity Level: 3-5 . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Values: Normal Numismatic Value

IV-A-2 Matte Proof on One Side (I), Rarity Level: 7. . . . . . . . . . . . . . . . . . . . .Values: Normal Numismatic Value

IV-A-3 Sandblast Proof (I), Rarity Level: 4-6. . . . . . . . . . . . . . . . . . . . . . . . . .Values: Normal Numismatic Value

 

 

Additional engraving (IV-B)


This section includes any added markings which are placed on the struck coin and struck coins which later were cut into pieces for various purposes. The warning is repeated: Anything done to a coin after the strike is extremely diffi cult t o authenticate and is much easier to fake than a die struck coin.


IV-B-1 Counterstamp and Countermark (I), Rarity Level: 3-6 . . . . . . . . . . . . .Values: Normal Numismatic Value

IV-B-2 Perforated and Cut Coins (I), Rarity Level: 4-6 . . . . . . . . . . . . . . . . . .Values: Normal Numismatic Value

 


Restrikes (IV-C)


Restrikes cover a complicated mixture of offi cial use of dies from a variety of sources. Whether or not some were offi cially sanctioned is always a problem for the collector.


IV-C-1) Restrike on the Same Denomination Planchet (I), Rarity Level: 4-6. . .Values: Normal Numismatic Value

IV-C-2 Restrike on a Different Denomination or Series Planchet (I), Rarity Level: 4-6

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Values: Normal Numismatic Value

IV-C-3 Restrike on a Foreign Coin (I), Rarity Level: 6-7 . . . . . . . . . . . . . . . . .Values: Normal Numismatic Value

IV-C-4 Restrike on a Token or Medal (I), Rarity Level: 5-6 . . . . . . . . . . . . . . .Values: Normal Numismatic Value
