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


Gemstone will be set up at Baltimore Comic Con on September 2-4, 2016.

If you're in town, come visit us at Booth 2313. We will have a selection of books available for purchase.



The 46th Edition  of The Overstreet Comic Book Price Guide is now available for order!



The Hall of Fame hardcover edition of The Overstreet Comic Book Price Guide featuring Sgt Rock artwork by Russ Heath is now SOLD OUT!!! We still have a limited supply of the softcover edition available, but the hardcover is GONE FOREVER! You may still be able to locate a copy at a comic book specialty retailer, but with a print run limited to only 1,000 copies, it could be hard to find!


 This year's edition features our first-ever connecting cover images, with 2 covers by superstar artist Amanda Conner. Each cover presents an amazing stand-alone image, and both placed together form one larger scene pitting DC Comics' super-heroines against super-villainesses!

Also available (in softcover ONLY! Hardcover edition has sold out!) is our first Hall of Fame Edition, with a brand new cover by legendary artist Russ Heath, and the oversized spiral-bound Big Big workbook edition featuring a beautiful cover commemorating the 50th Anniversary of Star Trek.

All editions except the Big Big book are available in both hardcover and softcover versions.


A special note to those placing pre-orders for upcoming publications...

In case you're wondering why your multiple-item pre-orders have been split, and are concerned about the shipping costs...

Due to a necessary programming function, pre-orders for multiple items or orders containing a combination of pre-orders and in-stock items are automatically split into separate orders for each line item. This occurs in case multiple pre-order items are received and shipping at different times. This allows each item to be filled promptly, without having to wait for other pre-ordered items to arrive.

We make every effort to fulfil your orders in as few shipments as possible, to minimize your shipping costs. Whenever we are able to ship multiple orders together, we will combine the orders and recalculate your shipping costs accordingly. Credit card orders are not charged until they are ready for shipment, so your shipping charges will be accurate at the time your charge is processed. If you paid by PayPal, we will refund any excess charges to your account once the revised and accurate shipping charge is determined.
