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



We've added a special offer to our product listings. We are making available a complete set of ALL 5 VOLUMES in our "How To" series of books for a special package price of $72.85...a discount of $15 off the total regular retail price of the individual books.


The Overstreet Guide to Cosplay is in stock and available for immediate shipping. Included among the available versions is a limited quantity of the Virginia Comic-Con variant softcover, as well an extremely limited signed & numbered version of the hardcover edition.

The Overstreet Guide to Collecting Movie Posters is in stock and available for immediate shipping.

Comic Book Marketplace Yearbook 2015-2016 is in stock and available for immediate shipping.


The Overstreet Comic Book Price Guide 45th Edition has been selling through at unprecedented levels, with 3 of the 4 hardcover editions already sold out, and 2 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.
