Yesterday I answered the poll as "Doesn't care one way or the other." I was going to qualify here in the comments that she is mildly interested, but I figured that "doesn't care" was a little more accurate.
So tonight at dinner I told her that I was going to be buying two more pins. She said, "Okay, that's great," and went on about her business. I had to ask her if she wanted to know what they were. So after tonight, I think my "doesn't care" answer is spot on. She likes having them and plays occasionally, but I don't think she really cares when you come down to it.
