If you don't need them for your collection, I'd say
ebay it. BU rolls will go for a few dollars each, which is a good return on your investment as far as cents go.
Can you tell what years you have? Some years have known errors or varieties that can be worth quite a bit. Break them open if you think you might have something special; otherwise leave them as-is and you can expect $3-10 each on
ebay.
