Here is the card you have:

They are marked as 1/1, but since they made 69 Strasburg cards (one for each of his career wins) Beckett has the cards noted as total print run of 69 with serial numbering out of 1 (i.e. each is a 1/1 but there are 69 variations). Due to this a lot of people don't value these as much as other 1/1 cards. That being said Strasburg only having 69 of these is not bad compared to some players that have hundreds.
