Introduced in 1969, one year after Shell Oil Company's very successful "Mr. President" promotional coin game, Sunoco's "Collection of Antique Car Coins"was the first true collector's promotion. This promotion was based on the 75-medal Franklin Mint "Collection of Antique Car Coins" that was produced over two yearsand in three 25-medal sub series.

Both series of the "Collection of Antique Car" coins can be found in Krause Guidebook of FranklinMint Issues (multiple editions) under the Franklin Mint catalog code ACG.
