Jason,
Great point, I've never thought about it from that perspective! That could get ugly, especially if she is a "type" collector and you are a "set" collector. That would be a divorce hearing I would love to attend.
By the way, here is a name of a lady collector..........Clara Schmitt Rothmeier who played first base in the 1950's for a touring women's softball team from Springfield, Il and was otherwise known for her baseball themed quilts. She recently pass-away at 78 and at the time of her death had more then 10,000 cards. I have her R311 Pie Trayner which I recently won in an eBay auction. Here is a link referencing her estate auction (perhaps, a couple of you junkies were in attendance?)......

FYI: the final bid price on her two autograph quilts was $72,700.
Lovely Day...
