[QUOTE="imrich, post: 8366350, member: 22331"]You sure are correct about long term storage of Copper cents. After 70+ years of collecting and storing semi-keys rolls of cents, I have some well-struck rolls of Green coins. I also have similar condition of contaminated/oxidized black Silver coins. Although I've developed proprietary means of partial contaminated reversal, the processes are time/effort prohibitive. I occasionally have a good laugh when I hear of the means for many postings long term storage approach. Although it isn't perfect for eliminating atmospheric deterioration, I found a slabbed coin will generally reduce surface deterioration effects. Generally, I've found that only a purged oxygen/air, vacuum sealed housing will eliminate deterioration. Expecting pristine rolls of wheat cents at virtually melt cost, wrapped in paper, is probably a little naive. fyi, AN INTERNET STATEMENT: How much did it cost to make a penny before 1982? So for the past 30 years, pennies have been made with an alloy comprised of 97.5% zinc and 2.5% copper, but pennies minted before 1982 are 95% copper and 5% zinc. The price of copper has more than quadrupled over the past 10 years. So a penny produced before 1982 is worth [B]2.2 cents[/B] based on the metal it contains. Feb 23, 2012 JMHO[/QUOTE]
