Buyer protection
Check the cert before the money moves.
PSA is the only grader with a public cert API this build can query. BGS, CGC and SGC are shown so you can see what is missing, not because a lookup is waiting behind them.
Enter a PSA cert number
We ask PSA what it has on record for that number and show you the answer. A match tells you the certificate exists — it is the start of checking a slab, not the end of it.
