Dated back a few months ago, I got a pm that asked me if I fixed my coin holder yet or got a replacement and from where.
Here is an easy fix, cost's a few bucks for:
1) Rare Earth Magnets (Radioshack)
2) Adhesive - I used Gorilla Glue, but epoxy and such, works just as well.
Basically, I glue the handle on the coin holder, cut the little latch off, glued the magnets into place. Works great, has a great hold so it wont fly open unsuspected.
(btw gorilla glue expands, it gets messy, dont use a lot of it

)
