From "The Early Coins of America" by Sylvester S. Crosby: "The first of these is called the New Yorke Token, and has until quite recently been considered unique, but within three years, three new specimens have been discovered; two of these are owned in Boston, Mr. Appleton having one in lead, and Mr. Parmelee one in brass. The other specimen is in lead, but its present ownership is unknown to us. The only specimen in lead accessible to us is so much corroded as to furnish no satisfactory basis for ascertaining its original weight.
The only account we have found of this piece, is in the Historical Magazine for 1861, from which we make the following extracts: 'The style in which it is executed is more Dutch than English; and as the only existing specimen has been preserved in Holland, it is probable that the dies were originally cut there.'"
The 1991 ANS Proceedings publication Money of Pre-Federal America contains an excellent study of the New Yorke Token by John Kleeburg, where he listed 20 examples that either appeared at public auction or were in institutional collections. Based on similarities between the eagle on the coin and the crest of New York Governor Francis Lovelace, Kleeburg proposes that these coins were made sometime between 1668 and 1673.
In the February 2005 issue of NUMISMATIST (page 63), William Anton offered a 1670 New Yorke Token in Pewter for $260,000.00, describing it as follows: "Gem Uncirculated with full square edges."
