I've just spent an hour or so scanning about 30 Mattingly cards. I feel a sense of accomplishment and am very proud of myself. Most people will think I'm crazy for doing this. I found a set that had inserts that were obtainable and that I actually liked. So I kept a watchful eye on eBay for the cards. I have to admit that once I got to the final 3 cards I went way overboard to get the cards. But I was so close to having every single card that I didn't care.
I like the 2008 Donruss Threads set. When I returned to the hobby I was upset to learn that Donruss didn't have a license. I was a Donruss collector back in the 90's and I really enjoyed their 94 and 95 releases. So I bought a box of 2008 Threads and pulled a
Pete Rose auto relic and a Don Mattingly base card. But I didn't stop there. I kept going.....

And the grand finale the Prime relic auto (#/10)


Well there you have it. It took a year but I finally collected every available Don Mattingly card from the 2008 Threads set.
I double checked my cards with the checklist found
here (it was the only one I could find).
So this is my obsession.
