Just to be certain, is this a brass coin or a silver coin with gold highlights? The latter will fetch more but still not what you're looking for.
According to Uberbills, it is a brass coin: https://casascius.uberbills.com/?address=13EyocNxqSpwMXMf1TvjX6AygLEPkySy9L

Current selling price of one of these coins is about $11,000 or less.
Thanks for that price evaluation.
Can you share some pictures? Brass coins in (near) mint condition will get you a much higher premium (but still not close to what you originally had in mind).
