It is tempting, but unfortunately the corrosion over the main determination points prevent a positive opinion. Here is a second photo from Coppercoins.com. and yours has corrosion in the same area also. It is not considered a high importance DDO, so many books don't show it in their listing. Bob got a nice coin to show his in photos. I can make out some lines in the 9 on your coin, but they seem slightly different, but they aren't clear in your photo, but it will give you another area to consider, Jim
