I dunno why there is a need to worry about silver prices; they are just part of the scene of commodity prices generally, and there has been a general trend down on overall commodoty prices for some time.
Why not worry?
I have had a passing interest in commodity prices for more than 50 years, when I bought my first gold coin. I have seen the market prices go up, and I have seen them go down, sometimes skyrocket and sometimes crash.
Been there done that.
And I still have gold coins,
and I still have silver coins, both numismatic and bullion.
And I am not the least bit concerned.
