Scott,
I would charge $795. These things are all gone and they have surely appreciated in value.
Seriously, I charged $25 for domestic shipping and $28 for international. I think they cost me about $21.50 each to have made. I wound up with a small surplus which was donated to the site.
I hesitate to bring it up again but we could do another run. The company that made them pings me regularly to see if I need anything else. I suspect we could do a nice belt buckle - that would be a truly period correct fashion statement!
