Mounting Indian Head nickle in a key fob

[TerraKacher]

I recently picked up four Indian Head nickles at an auction, got a good price for them.  I was thinking about mounting them in a key fob blank.  They measure about 7/8 of on inch in diameter.  I was thinking of cutting a 3/4 inch hole in the center of two blanks.  Then glue the two together with the nickle in the middle.  Then stitch around it.  I belong to a treasure hunting club and it would make a great gift or auction item.  So my question is, what is the best way to cut the 3/4 inch hole?  I've been searching on google, and there are plenty of cheap punch's.  I do have a 5w laser engraver I could use.  But I wanted to get your thoughts about this.

Personally I'd use a hole punch. Mainly cos have one that size. I'd also use one with can be used in a press, and I have one of those too. I think a good sharp punch can give a good clean cut
