Are you talking about the credit card sized $10 coupons? If so, I used a couple about a month ago and they were accepted. They were about a year and a half old, but they didn't have expiration dates on them. They just scan them in during checkout and the $10 comes off the purchase.
If you're giving them away, I'd be happy to take them off your hands. Will even send you a self-addressed stamped envelope!
