I like the Sacs and this year I was really impressed with the Pres for once. BUT these coins do NOT circulate well. They tarnish after a single handling. Do this...
Roll a new example around in your hand for about 30 seconds and then set it aside for a month or so. You will come back to brown nasty looking coin. The finish just does not hold up. Not sure what they could do to improve that though.
It is could've, would've or should've, not could of, would of or should of.
