I’ve had to arrest people and successfully prosecuted them for passing fraudulent money and deception. 

Anyone attempting to pass counterfeit money given a receipt will not give their real details and will move on to the next town with their wad of home made cash. 

I have a small safe full of counterfeit money I’ve previously used for training material both paper money and coinage – some dating back 40 years. 

I think that’s fair. Money that nobody recognizes as real isn’t very useful after all.

I think letting it sit in a box in the closet for years until I have grandkids is a great idea (it will be sitting along with all kinds of useless but neat stuff – not sure if my grandkids will love it all or will be annoyed when they have to get rid of it all when I die).

And I’d keep them, give them to your grandchildren who will no doubt look at you with wonder at how people traded physical coins in the ‘olden-days’. Plus they will be worth much more in a few decades. If you do sell, avoid pawn shops, coin dealers, jewelry stores, and metals exchanges, most of them are consummate cheats. And unfortunately it’s a little hard to get a fair deal on a few coins (YMMV). Again I’d just keep them.

Link, please?  I know some shockingly ignorant rich people and have known a lot of amazingly knowledgeable poor people.    College physics professors make far less than stock brokers.    People with masters’ degrees are flipping burgers part time.
I guess my point is 
(a) I am not convinced your statement is even true as a statistical matter, and would like to see a link; 
(b) you need to define rich and poor; and 
(c) even if your statement is true statistically, lots of individual poor people are a lot more knowledgeable than lots of individual rich people.  

ebay?  dunno – my silver coins have been sitting in a box in my closet for years.

So yeah, feel bad for the kid because he’s an idiot but feel worse for the person they ripped off in the first place.

Here, though, I feel strangely compelled to say…Yep, we’re idiots.

That is indeed a 1964, and the other is 1980 unfortunately. Thanks for the info! Not sure what I’ll do with them, the 1964 coin isn’t in great shape (maybe silver polish will restore it?)

I spend a lot of money at that thrift store, and I’m actually just about to donate a huge load of high-quality stuff this week. I’m not worried about my karma in that regard :)

The lower one appears to be a 1964, which is 90% silver, and worth around $11 today just for the metal in it.

I can’t read the date on the other Kennedy half.  1965-1970 Kennedy halves are 40% silver, anything newer is likely worth just $0.50.

That said, karma demands that if that thrift store is run by a charity you pretty much have to share your good fortune with them, though karma will go easy and allow to take a tax receipt for your donation.
