Okay! That's about 19mm larger than the Enterprise medal. Don't carry it in your pocket without wearing a belt, Tommy! Chris
I believe it will fit in the "monster" slab that NGC used for my 1876 Philadelphia Exhibition which is 76mm x 9mm thick. I think NGC will slab medals & coins up to 115mm or so. Chris
At one time I owned should say had in my collection an year of the Tiger 1/2 kilo ! It was the size of a desert plate. I had all of them from 1/2 oz- to 1/2 kilo. I kept the 1/2,1 & 2 oz. Coins. Of course when silver was $40+ some of the bullion had to be sold. Hated to do it but.... couldn't help myself from a huge profit .
