I'm still not looking to complete a rainbow, not even close. However, right after the gold Jeter arrived, I found a rainbow copy of the checklist card for way cheaper than I thought I'd be able to. So, a BIN later, and all of a sudden this card is on its way to my door.
In he span of a few days, I took two steps closer to completing the parallels I wanted to put together. Three down, one more to go. If anyone out there has a rainbow foil copy of Jeter #1 that needs a good home, I can help with that.
