Went through (1) $500 box and $130 of my second $500 box tonight. Found four 40%, (1) 1996S clad proof, and my first commemorative half (1992P Olympics).
Nice find Ify ! I've come across an Olympic comm (basketball '96; I think) once. They are pretty cool.
On your proof, it would be helpful (to our collective curiosity, not to mention Gman's tracking) if when someone finds (and posts about) a post '91 half; they additionally specify if it is silver or CuNi (as the has Mint produced both since '92).
