Welcome to Gemstone Publishing, Inc., home of The Overstreet Comic Book Price Guide and much, much more.


The Captain America and S.H.I.E.L.D. softcover is the latest version of The Overstreet Comic Book Price Guide to sell out! The 45th Edition has been selling through at unprecedented levels, with 3 of the 4 hardcover editions already sold out, and now 3 of the 4 softcover editions are sold out as well! Get yours before they're gone!


Also available in rapidly dwindling quantity is the large spiral-bound Big Big workbook edition.

In the aftermath of our warehouse relocation several months ago, copies of a number of out-of-print publications long believed to have been sold out have been turning up during our ongoing process of conducting a comprehensive inventory verification. Over the next several months, these will be added to our roster of books available for sale.


One of the first items to be added is our 2007 publication the Official Price Guide to Mechanical Banks. We have an extremely limited quantity of this hard-to-find volume now available for purchase at the original publication price of $24.95.
