HI GUYS. I AM INTERESTED IF ANYONE KNOWS EXACTLY WHAT THE DATABASES ARE CALLED FOR AUTHENTICATION COMPANIES LIKE UPPER DECK, JSA, PSA, TRISTAR WHERE YOU INPUT SERIAL NUMBERS ONLINE AND UP OPOS THE FULL COA? WHERE CAN I GO TO MAKE ONE OF THESE TYPE DATABASES/REGISTRIES? ANY AND ALL INFORMATION REGARDING ON HOW THESE WORK AND WHAT YOU KNOW ABOUT THEM IS GREATLY APPRECIATED?

If they are slabbed cards, you can cross reference graded or encapsulated cards/memorabilia right on the PSA and Beckett web sites. You cannot add your own entry if that's what your asking.
