This is tricky since I don't have the band anymore. So what I did was feel a bunch of my yarn and picked one that was as similar as possible. It was 70% acryllic and 30% wool. The percentages are probably close because that's generally what I buy. No guarantees though. Best I could do to answer your question. Hope this helps.
Thank you for posting a pic with your hand, the quarter and ruler. This is a big help. I feel bad, because after all that you think there's wool in it and I'm allergic. I do hope your auction(s) go very well for you though.
