The US Mint has estimated 1-2% attrition rate for circulated coins.
Looking at just 1938 mintages, thats a total of 28,977,000 nickels minted. If we estimate an attrition rate of just 1% per year, thats 73% attrition since mintage, so only 7,823,800 1938 nickels are remaining in circulation. Now consider the spread when 1938's are mixed in with 72 additional years of minting.
