Having had an interest in coins since I was able to grasp the concept of the value of metals I have taken to asking the local bank for any "rare" coins half dollars and the like, and I do believe I have finally found something worth asking about, 8 Eisenhower dollars, 3 bi-centennial, 3 72's and a 74 and a 71, I am honestly not sure where to find the mint marks however one of the 72 has a heavy green patina (although it could just be dirt there seems to be a bit of what appears to be green crayon stuck to it...) The rest are in very good condition almost uncirculated in appearance...
