As some may know, I mainly collect Barber and Seated Half dollars. I use this site a lot, and it has been very helpful. It's free, and there are some helpful books for collectors of other series. Have fun, I know some of you may know about it, but I figure a lot might not. http://blog.davidlawrence.com/index.php/david-lawrence-rare-coins-reference-library/
Great information in there. Thanks for the link. BTW David Lawrence also sells some great coins, some really high end stuff. I think it's his son that's taken over the business now?
Yes, David Lawrence passed on a few years ago, and his son runs the business now. They offer mostly high end coins.
