Comments

1982 edge letterings. The small letters are about 1.1 to 1.2 mm. high, while the large ones are about 1.6 to 1.7 mm. high.

1982 edge letterings can be found facing obverse or reverse.

Differences between the 1980, 1981, 1982 and 1984 dies. The 1980 die has 51 C-shapes in a chain next to the edge, the 1981 and 1984 dies have 48 such C-shapes, while the 1982 die has 44 C-shapes. The C-shapes on the 1984 die are a little more spread out than those on the 1981 die, the second A in ‘MAYA’ falls below the 12th C-shape on the 1981 die, but below the space between the 12th and 13th C-shapes on the 1984 die.
