Chess Stamps

I have a collection of all chess stamps.
All are mint condition, new, not used.
I have 200 chess stamps from 50 different countries.
None are rare.
Sent them to one large company, they sent them back, lost my shipping fee.
Emailed 3 large companies, no interest at all.
Estimated retail is $800.00
I know I cannot sell yet, only have 140 comments.
Could anyone that is interested give me a pm.
It works on the coin side, if it does not work here let me know.
I retired 18 months ago and must sell some things.
If someone is interested let me know.

apparently the 140 on the coin side does not count here
