I recently acquired this penny in a lot I bought. It came encased in the airtight. At first, I thought it could have been accidentally struck on a steel planchet or plated, but it doesn't stick to a magnet. Thoughts?
probably one of those science experiment coins. pennies can be zinc plated using sodium hydroxide and zinc powder. 1960 wouldn't be a steel planchet. It is a possibility it could be on a silver dime planchet, but the coin would be much thinner than a normal penny. 99% of the time it's just those school science experiment coins.http://www.youtube.com/watch?v=q4puQhfJg-o
galvanization is zinc coating draino contains sodium hydroxide. any combination of zinc and sodium hydroxide will do it i have done it with bb gun bb's and fish tank test solution. or liquid bluing and any other zinc you have.
Yeah. I cracked open the holder and checked the edge. The copper shows through. I think we have a science experiment victim. Cool looking either way.
