Not too many...Although they are legal currency! I have some from when I visited the US Mint in Washington DC from years ago. They are probably worth quite a bit in a place like Venezula.....

I have a few, but they are in my "interesting money" jar along with a couple silver certificates, a dollar bill with a lot of zeros in its serial number, a handful of silver coins from when you still found one occasionally circulating and some non-Canadian foreign coins.

Maybe I need to separate out the old fashioned Lincoln Memorial pennies like I used to do with wheat pennies.
