Ok, slow down and hold up. Things are running away with themselves. Firstly, do you want to sell the coin? If you do you stated that you've had persons asking how much, so how many people did you email? Are all fremch coinage experts? If so, play them against each other IF you want to sell. Ask THEM what they're prepared to pay and not what you want, you may get a large Variable in price if you have 3 Potential buyers. Take things slower and don't rush, you may eventually rue the day
