How to read the listings

The first word is the coal camp or town, in this case, Ages, along with a number assigned by the scrip association.
The company name, exactly as it appears on the scrip piece, is next. In this case, Ages Supply Co./Ages, KY.
The first column is a series letter (B in this case) and the denomination, 5, meaning it is a 5¢ piece.
Next is the composition, A, for aluminum, as in this case. B is brass, bronze, or copper. Bi is bi-metal. N is nickel, Np is nickel plated. Z is zinc.
The third column is the diameter to the next highest millimeter.
Fourth column is the shape of the token. Sc is scalloped rim, Hx is hexagonal, Ov is oval, Rd is round.
The fifth column says Sd if the token is solid, Co if there is a cutout. A drawing of the cutout is shown.
The next column shows the words on the reverse, and in most cases, the manufacturer of the piece.
Last is the rarity rating. R-1 is the most common, with 300 or more pieces known to exist. R-10 is the most rare, with 1 to 4 pieces known to exist. R-9 has been assigned to this example, with about 5 to 9 pieces known to exist.

The value of a piece depends mostly on rarity and condition.
