Please note: the error types listed below were ebay lots that closed with a high bidder. If the reserve price was not met, or picture was not attached, then I ignored the auction. Fuzzy pictures, or questionable descriptions are not included.
An important observation about 5c “Speared Bisons” and the 25c Wisconsin extra leaf errors sold on eBay is that 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. An example graded PCGS & NGC MS63 can be purchased for $125 or less.
The higher leaf may not be as rare as previously thought. The high and low leaf are starting to sell for the same price range. The high leaf may not be as rare as previously thought.
