2015 Upper Deck Goodwin Champions Multi-Sport Forum

I have 2 Marcus Allen cards, 18 and 117, and both have that "canvasy" look and feel, but they are not serial numbered.

The Mini Canvas insert set has a print run of 99. Here is your card of Marcus Allen #18 on COMC.

It would appear that the notes for that set should read "PR99" instead of "SN99".

So a print run doesn't have a serial number necessarily on these cards?

And how do we 'know' the print run? Does Upper Deck release print runs for these cards?

beckett usually shows the prints and has describtions on the products.. and depending on the year you can find information on the MFR websites

Correct, that is the distinction between the two.  For it to be a serial number, each individual card has to have a unique identifying number on it.  Print Run is used when every card in the series has the same "1 of xx" printed on it, OR when the population of the card is otherwise known.
