You forgot the escrow part. There will be no sending of payment to you first. Here is a list of forum escrows:

https://bitcointalk.org/index.php?topic=2439910.0

The way this works is the escrow holds the BTC, LTC or ETH until you successfully send the STQ to whoever buys them (assuming someone even wants them). When the buyer confirms you sent the STQ, then and only then will escrow release payment to you.

Safer than someone sending 0.5 BTC or almost $6000 to you first. Am I right or am I right?

Yes, using escrow is the best way to avoid fraud or loss, but remember you have to use the escrow that is enriched so that all transactions can be done safely

I would not trust this site.  Nothing personal but the "thank you sir" is kinda creeepy and scares me to the point that you would close down if money became tight

I have a quite a few pieces, some for sale some I would probably want to keep.  Most come with original certs + email/paper receipts from artist or gallery.

Pieces that looked creased are just in an acid free art folder and are in perfect condition.

If there are any pieces you like I can take better pics along with my username + date on a bit of paper alongside, Escrow with any of the bigger hitters here is also ok with me.
