I have no information on US pattern coins struck prior to 1863. What I do have is proof that in Mayand June of 1863, a few aluminum pattern Postage Currency coins were struck. The dates of striking and the quantities were well documented. As todating the striking of these coins, May 19, 1863, S.H. Chapman & H. Chapman in the George Eavenson Collection were documented from the MintDirector Chase's "Mint Report of 1863." Usppcc pg. 121

Plate 8, page 142 of my book "United States Pattern Postage Currency Coins" (published 2007) pictures the original wrappers containing theinformation in the handwriting of Mint Assayer, William E. DuBois presented to Mint Director, James Pollock, and then to Salmon P. Chase, Secretaryof the U. S. Treasury during the administration of President Abraham Lincoln. "No. 3 Aluminum 2 pieces. 10 cts each weight 8 grains, value about 5cents, each."

The ten coins pictured on five wrappers were discovered in the early 1960s hidden in a time capsule that was discovered when a Dallas bank wasremodeled. Milton R. Friedberg bought the coins and wrappers and later sold them at auction. Quoting:

The first recorded sale of these aluminum coins was by Ed Cogan who catalogued the sale on June 29-30, 1864, Lot 758, Aluminum.

On October 16 thru 20, 1865, Ed Cogan sold Lot 2057 as an Aluminum coin. Although unpictured, the written description of these coins is that of aPostage Currency ten cent coin.
