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

While The Overstreet Comic Book Price Guide is the foundation of our company, our coverage of pop-culture collectibles is much more expansive. Be sure to browse our site and see what else we have to offer. From movie and concert posters to gaming to cosplay to Star Wars and beyond, we publish books to cover all of your collectible interests, with more to come!

Delayed shipping alert!

We and our sister company Diamond International Galleries are currently in the process of packing the contents of the warehouse and offices we share, and relocating to a new facility about 5 miles from our current location.

Since we are making this move with no outside movers (we learned from that mistake after our last move!), we are not able to monitor and fill orders as quickly and efficiently as is our normal practice. We are hoping to be fully functional in our new location by late April or early May. Our contact information will be updated here once the move is complete. We ask for your patience and understanding during this transitional period.

Important note for 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.

We strongly recommend paying by credit card rather than PayPal if you are placing a pre-order. Credit card orders are not charged until they are ready for shipment, so your shipping charges will be checked and adjusted for accuracy at the time your charge is processed.

If you pay by PayPal, your account is charged immediately. This then requires that you carry a possible shipping charge overpayment until your pre-ordered items are ready to ship and the actual cost has been recalculated. We will refund any excess charges to your account once the revised and accurate shipping charge is determined, but depending on how far in advance of publication date you place your order, it could be weeks or even months before you get your refund.
