Welcome to JM Sports Cards
JM Sports Cards began in 1999 as cowboycards.com. I sold Dallas Cowboys football cards for the better part of 2 decades and did well for the first half of that tenure. Somewhere in the mid 2010s, sales began to fall off and eBay slowly took over the online sports card arena. Eventually I retired my site (Cowboycards.com) and began selling my cards on eBay. I have yet to recoup the success of the early days on cowboycards.com but I still love buying and selling sports cards.
After moving my inventory to eBay I began expanding and selling other sports and other teams. Today I enjoy the thrill of opening brand new packs as well as searching for those vintage finds located in someone’s attic. If you have cards to sell, please reach out to me at [email protected].
