I can best be contacted at pknapton@hotmail.com or via the address at the top of the page. I try to answer all emails within 48 hours. If sending me a letter please include a SASE for my reply.
I also buy coins. I am always looking for scarcer and older material. If you have any US or World coins for sale please send me your list of what you have.
Please do not send unsolicited material to me for review or authentication without prior instruction.
