Ok so I went through 400 presidential coins and I found a Harry S Truman dollar coin 2015 and I'm wondering why it is void of the gold color this is the only one out of the 400 that looks like this is this just a worn-down coin or is it missing it's gold color from error?
Even though the Truman Dollar was not released for general circulation, a lot of Golden Dollars loose their luster when in circulation for a while. This coin shows no wear of use, so I agree with paddyman98. It was exposed to some kind of chemical or other environmental agent causing the loss of shine and luster.
"From 2007 to 2011, presidential $1 coins were minted for circulation in large numbers, resulting in a large stockpile of unused $1 coins. From 2012 to 2016, new coins in the series were minted only for collectors."
