Here is all that I know. I purchased one set about two yeas ago from a dealer who only had the one set. I believed these to be very rare at the time, and was hopeful that the set would sell for $1000. I offered the $100 on ebay about a year ago, and the only bid was $100. As such, I tired to price these reasonable. I have no details on any other transactions. I am sorry that this is not much information, but it is all that I know.

Regards,

John
