Thanks for replacing the image on the OP as well as on your auction. Again, the stamp already has small perf problems but a bidder would be more confident in knowing that there are no hidden problems if you photographed the back in addition.
Rather than looking at current
ebay bids, you should consult the sold listings using the checkbox in the sidebar. It is still very early days for the auctions you mentioned above; any realistic bids are generally made at or near the last minute.
