Another conservation success

I decided to crack out an MS63FH Standing Liberty Quarter, as it had some gruesome looking black spots on it. While it didn't remove EVERY spot (I didn't dare keep dipping it), it removed enough that PCGS upgraded the coin from MS63FH to MS64FH.

YMMV of course, buyer beware. EZ Est is VERY potent!
