If simply wishing to show off what you have, kindly start a thread to do so. However, if you're trying to sell them, this is frowned upon in the open forum, but once you've over 10 posts (iirc - with patience), you can list in the "for sale" section.
You expect him to actually check completed sales and stuff when he could just ask the people here? Psh.
Generally, I believe you'll find they're worth whatever a buyer and seller agree to pay/sell. I sell large lots of mint-marked Mercury dimes in that condition to my grand-daughter for $1.30. She sells them in various venues for $3-$5.
