USB Microscope Recommendations

Hi all,

I'm looking for recommendations for a decent USB microscope. With the impending demise of the penny, my local banks have stopped selling us boxes of pennies as they cannot get them themselves.

Dad and I are going to start looking through more nickels and half dollars now... the only issue is that his eyesight isn't good enough to read the dates. He'd tell the wheats by looking at the backs.

Hoping to get a good USB scope that's relatively easy to use, doesn't cost a ton of money, and can function by having someone place a coin under it and then have it be able to show the date of the coin on a computer screen.

Also, if this scope could be powerful enough to identify some errors, like RPMs and minor DDs, that would be very helpful too.

Any recs would be great! Thanks!
