The picture below show larger front and back views of this Old J. H. Pollack Advertising Good For Token Coin. The token is not dated but it is believed to be from the 1920s or 1930s. What we found is that J. H. Pollack may have been a bicycle sales and repair shop around Oshkosh, Wisconsin. The coin is made of aluminum in an odd shape, and it is marked on the two sides as follows:
J. H. POLLACK 809 OREGON ST. PHONE 4387
GOOD FOR 5c IN TRADE
The advertising token coin measures about 1'' wide. It appears to be in excellent used condition as pictured.
