There are a lot of defunct siver mines out there. See if any are listed or watch for them to be. Ideally, mothballed with the lease and operating liceence still active. This means they can be reactivated quickly and come to marlet fast. Plenty of silver out there but it was not economic to mine at $5 and ounce back aroud 2000 so many closed.

There are also gold ETF's but you need to make sure they do actually have the silver in the vault and not a 'right'.

Hard part with buying physical is storing it, safe deposit boxes work well but gold is better in that its worth a lot more and therefore easier/cheaper to store.
