Yikes!
The seller in this case does not usually sell thimbles. I often wonder what eBay sellers who aren't familiar with crazed, voracious thimble collectors must think when they see their auction prices fly out of the park as this one's did. This seller's other auctions have all been for jewelry--Tiffany, David Yurman, et al.--and haven't approached half of what this one little thimble went for.
