Seriously...I would buy a Redbook and Strike it Rich with Pocket Change and start looking at values. The Redbook gives high values for graded and slabbed coins. You can expect a little less, but it will give you a ball park that can be further compared to completed e-bay auctions.

What do you mean? How is this different from other doubling?

it looks just like the one in this book : http://www.amazon.com/Strike-It-Rich-Pocket-Change/dp/1440235708
and isn't Ken Potter a respected authority on the subject?

I hear you. Striking it rich with pocket change. Helped me out a lot in the beginning. I love being able to sift through my change looking for something mare than face value.

Nice score! I recommend this book to anyone interested in finding error coins and die varieties in your pocket change. It's fun and people find them more often than you'd think.

Something somewhat related coins with errors you can find in your pocket change... some are pretty unnoticeable and can be worth a few dollars, while in general the more noticeable ones, if you are lucky enough to find in circulation, can be worth hundreds or thousands. If you're interested this book has a lot of the ones worth more than 25 cents listed in book (or pdf you may be able to find online)
