Never 'suppose' anything. If you want to sell it you need list it and find out if anyone will buy it ! Just because you were willing to bite the hook doesn't guarantee anyone else will. Besides if you go to sell it there are almost always costs involved. If you have doubt you need remember that there exist thousands of examples of this coin in dealer inventories and private collections. Never mind any being found in the fields of Europe by weekend warriors out and about metal detecting. If you have doubt don't do it. At $140 it isn't being given away.
