As a side-effect of other work, I have produced a file of prices for U.S. coins, based upon three separate coin price lists for 1980. I do not intend to update this list, and have no access to more recent or complete data. I am offering this data on the assumption that someone may find the data interesting or useful, and that some data is better than none. The remainder of this posting is the README file explaining the contents of the file; the next posting will be the actual data file itself. The file "coins80" contains a list of the prices of various U.S. coins. This file describes the contents of the "coins80" file. Each line of the "coins80" file describes one coin. There are 2397 lines, each an average of 97 characters long. Each line is a set of fields. The fields are separated by semicolons. The field contents are: Field Contents 1 Face Value of Coin 2 Type of Coin 3 Date and Mint Mark 4 Design of Coin 5 Comments (if any) 6 Mintage 7 Price for Almost Good Condition 8 Price for Good Condition 9 Price for Very Good Condition 10 Price for Fine Condition 11 Price for Very Fine Condition 12 Price for Extra Fine Condition 13 Price for Almost Uncirculated Condition 14 Price for Uncirculated Condition 15 Price for Proof Condition The entire file is sorted, first by Face Value, then by Date and Mint Mark. The file is a result of scanning 3 coin books from 1981. The results were then reformatted and checked. About a month was needed to correct scanning errors. Field 1. Face Value of Coin This field is mainly to aid in sorting the file. There are ten possible values for this field: 01, 02, 03, 05, 10, 20, 25, 50, 100, and 300. The 300 value is used for proof sets. Field 2. Type of Coin This field is the name of the type of coin. The following table gives the combinations of field 1 and 2 which occur, and the number of each combination. Number Field 1 Field 2 ---- --- ----------------- 435 01 Penny 14 02 Two-Cent Piece 53 03 Three-Cent Piece 106 05 Half Dime 238 05 Nickel 418 10 Dime 7 20 Twenty-Cent Piece 398 25 Quarter Dollar 420 50 Half Dollar 236 100 Dollar 26 100 Trade Dollars 45 300 Proof Sets Notice that Proof Sets have a "face value" of 300; both Nickels and Half Dimes have a value of 05 and both Dollars and Trade Dollars have a value of 100. Field 3. Date and Mint Mark There are 460 different values for this field. The dates run from 1793 to 1980. If a mint mark is present, it is separated from the date by a space. Mint marks include D (333), S (493), O (177), CC (55) and P (26). There are 1312 entries with no mint mark. Field 4. Subtype of Coin This field lists the name of the design of the coin. The following combinations of Field 2 and Field 4 exist. Number Type SubType ---- ---- ------- 2 Penny Braided Hair 91 Penny Coronet 47 Penny Draped Bust 4 Penny Flowing Hair, Chain 3 Penny Flowing Hair, Wreath 4 Penny Flying Eagle 57 Penny Indian Head 12 Penny Liberty Cap 59 Penny Lincoln Memorial 142 Penny Lincoln, Wheat Ears 14 Penny Turban Head 14 Two-Cent Piece 27 Three-Cent Piece Nickel 26 Three-Cent Piece Silver 12 Half Dime Draped Bust 2 Half Dime Flowing Hair 14 Half Dime Liberty Cap 78 Half Dime Liberty Seated 68 Nickel Indian Head or Buffalo 114 Nickel Jefferson 34 Nickel Liberty Head 22 Nickel Shield 16 Dime Draped Bust 31 Dime Liberty Cap 76 Dime Liberty Head 122 Dime Liberty Seated 80 Dime Mercury 93 Dime Roosevelt 7 Twenty-Cent Piece Liberty Seated 5 Quarter Dollar Bicentennial 6 Quarter Dollar Draped Bust 28 Quarter Dollar Liberty Cap 75 Quarter Dollar Liberty Head 122 Quarter Dollar Liberty Seated 38 Quarter Dollar Standing Liberty 124 Quarter Dollar Washington 6 Half Dollar Bicentennial 14 Half Dollar Draped Bust 4 Half Dollar Flowing Hair 35 Half Dollar Franklin 38 Half Dollar Kennedy 73 Half Dollar Liberty Head 123 Half Dollar Liberty Seated 65 Half Dollar Liberty Walking 62 Half Dollar Turban Head 10 Dollar Bicentennial 26 Dollar Draped Bust 20 Dollar Eisenhower 3 Dollar Flowing Hair 47 Dollar Liberty Seated 99 Dollar Morgan or Liberty Head 24 Dollar Peace 7 Dollar Susan B. Anthony 26 Trade Dollars 45 Proof Sets Field 5. Comments (if any) Some coins (538 of the 2397 listed) have comments indicating special properties of the coin or variants. The most common comments are: 39 Normal Date 24 Small Date 22 Large Date 13 Copper-Nickel Clad 12 Silver 11 Arrows 9 No Arrows 9 Small Letters 9 Large Letters Field 6. Mintage Mintage is generally given as a large integer, with embedded commas to indicate thousands, millions, and billions. These values range from 400 to 5,505,275,000. Missing or unknown values are indicated by a field containing a single dash "-". Some coins are known to have only a few existing pieces; these are marked as "(Rare)" in the Mintage field. Fields 7 to 15. Price Fields The price fields contain the prices for each coin for each condition. Missing data is represented by a "-" field value. Values range from 0.05 to 520000.00 (1804 Draped Bust Dollar in Proof condition). Values increase with condition.
