Sell Your Cards Here

We specialize in graded baseball cards from all eras, but our "sweet spot" is Post-WWII cards from the 1940s thru the 1980s. 

Selling to us is the easiest and quickest way for you to get cash for your cards.  What you will get from Diamond Cardboard is an honest appraisal and fair offers.  We even keep a Buying Price Guide readily available for your convenience and visible for all to see.  

Our buy prices are based on current market trends and the types of cards.  Hall of Fame Rookie Cards are always in high demand and we can offer the highest rates on these.  Whether they are HOF Rookies or mid-grade commons, I think we can offer you a great package that is as good or better than any competitor.  Just take a look and give us a try!

***Note that this guide is not complete of all cards that we buy.  Message us with any questions or inquiries.

We offer 3 ways to get paid:

After sending us your consignment form and scans of the cards...

1. Quick Cash

We will pay you any amount up to 50% or $1000 of the agreed consignment value, whichever is less.
You choose the amount that you would like paid, but keep in mind that this payment must be via PayPal Goods where your payment will be reduced by their 2.9% in fees.
When your package is delivered to us, we will pay you the remainder of your consignment value via a mailed check or regular PayPal (without fees).
In the end, you receive at least 97% or the consignment value.

2. Standard

When your package is delivered to us, we will pay you the entire 100% of the consignment value via check or PayPal (without fees).

3. Maximum Pay Out

Take no early payment and then in no more than 1 month after your package is delivered to us, we will pay you 105%** of the consignment value  via check or PayPal (without fees).  This is still quicker than any auction house consignment payout and allows you to absolutely maximize your profits.
**This percentage value is subject to change, but once your consignment is received, your rate is locked in.
