An important observation about 5c “Speared Bisons” and the 25c Wisconsin extra leaf errors sold on eBay. There is little to no demand for the “Bison” errors from collectors or dealers at major conventions. The demand for these on eBay are way down in price. There were many auctions listed but failed to attract any bidders.
The Wisconsin leaf errors have dropped in price substantially. Unlike the “Speared Bisons”, there are collectors and dealers asking for these varieties at conventions. Check out the new prices realized below, then compare them to an older price guide.
