I completed my search of 283 large date 1995 S5Y. Of 283 coins searched, there are 38 var-B+var-C, or roughly 1 in 8. Var-B is harder to find, there are 13 out of 38. There are 25 var-C out of 38.
I would like to add to above statistics reported by SANDAC as I just finished sorting 626 1995 S5Y LD. Thanks again to dc55232 who provided me most of the NGC cert numbers.
Totally graded by NGC: 698, in my data file: 626, no photos - 11, mislabeled - 3.
Var A - 513, Var B - 31, Var C - 68
Disclosure: I own several coins of the Var A and Var C. Other varieties I discussed before (the 1994 S5Y and the 1995 SD frosted/mirror gap) I own none.
