Has anyone found 2017 coins in circulation?  It seems strange that 2017 is 5 months old and I have not found a single 2017 coin in circulation.  Doesn't this hurt the hobby?  YN's are frustrated because they cannot find current year coins.  Last week the Mint sent email stating they have minted over a billion new 2017 P mint-marked cents just by itself.  Where are they - sitting in Federal Reserve vaults?
