I have mostly bars and rounds, and just a few numismatics. Pretty much exactly the same thought process you went through about security issues. Although bars have a potential to be divisible in a way you wouldn't want to do with numismatics, say if you ever found yourself needing to buy a loaf of bread of a tank of gas with silver.

Although one quick tangent. When hurricane Katrina hit, the infrastructure did collapse for a bit. There was no gas coming in because the roads were flooded. Electricity was out. Not everyone had water. We managed to scrounge a little gas from a motorcycle, and we were absolutely induated with offers of goods for a ride. And we turned everybody down because what good is a gold watch when fuel was priceless. That's some real SHTF currency right there. Too bad gasoline doesn't store well.

It's not a big collection. I was very enthusiastic about the silver market when I first got in, and it certainly hasn't lost me anything, but as far as investments go, accidentally leaving change in bitcoin from a transaction totally eclipsed any potential silver returns.

That's when I decided it was smart to have a cache of silver but it wasn't going to make me much money.

I do have a 2 oz Canadian bison coin that's awesome. I have read of Canadian silver having a problem with milk spots, that's kept me a little wary of buying Canadian.
