The barcode is these digits put together: six digit PCGS Coin Number, 2 digit Numeric Grade, 8 digit Cert Number.
Sometimes fakers will copy arabic digits for these matching the coin in the holder,
but will fail to make the corresponding barcode. We have discussed this in a few old threads.
The barcode in this photo has the PCGS Coin Number correct, but the grade and cert number wrong.
