Over 30 years ago I found a claded (silver,copper,sliver) 1969 penny and was offered $50 for it by a collector. I didn't bite on the offer and then misplaced the penny until I recently found it again. The coin is also slightly smaller than a regular penny. Anyone ever heard of such a coin?
You appear to have a cent struck on a clad dime planchet or blank. Uncirculated specimens bring around $200 - $250 today. They're a readily available error type, appearing all the time on eBay.
