John, It depends on how 'good' your good is. Coins are graded precisely, and the value depends on the exact amount of wear. If they are both very circulated they will be worth very little. There's some useful info on grading and the scarcer dates in my advice hub: http://www.predecimal.com/coinadvice.htm If they are good enough to cover the postage costs, you can sell them to me, I always offer 60% of what I hope to eventually get for collectable coins. You can email me cp@predecimal.com
