Actually I don't think you will find a 1939 Henning on eBay. I have only seen 1944 Hennings on eBay. IMO the 1939 is more valuable then the 1944 Henning. I have a wanted ad on this forum looking for a 1946, 1947 or 1953 Henning nickel offering $250 to the first one of each date offered to me. I have two 1939 Hennings so I didn't list it in the wanted ad. If I saw this Henning on eBay I personally would go as high as $150 for it. This should give you an idea for an estimate. I should also point out you don't have enough posts on this forum to offer it for sale here yet. With all of the past posts about Hennings here I would think this site should be a great place to sell it if that is what you have in mind and I would suggest actively hanging around to sell it here at some point. If you don't want to sell it and keep it for your collection then I certainly understand. I know I would keep it. Again, nice find and congrats!
