I'm so glad I invest in gold and silver, but my best investment recently, actually, has been what is called "junk silver".  You can choose from quarter or dimes but I like the dimes.  I bought one bag of quarters, but the rest I bought in dimes from the 1950's and 1960's.  YOU SHOULD TOO IF YOU'RE WORRIED ABOUT ANY OF YOUR OTHER INVESTMENTS RIGHT NOW, as you probably should be. 

You certainly cannot depend on social security and medicare these days.  biden will get rid of them if he has a chance, just you wait and see.

Here's some information, only I buy my stuff through Money Metals out of Boise, Idaho.

I also have many "Walking Liberty" half dollars.  You also need to have a home safe or buy one if you're going to invest in coins.  Just stashing them somewhere is not a good idea, you must keep them protected.
