0.65 Troy oz. of silver? seems like an odd number.
So literally an old Canadian dollar, 0.60 oz. Ag, is exchangeable for the Brass Ring version of the gaming tokens. I guess this Hurrah's token is a little more special.
The brass ring is meant to protect the silver part of the token but give it a bigger look. Personally, it adds too much bulk and I would have preferred it without the ring anyway.
