Big D, do you want to be my partner, I was thinking along Main Street in Grapevine.
Also, I'm wondering how much money is left to be made from someone discovering in their attic a 1916 - D Merc and walking in and saying will you give me a quarter for this? I don't think there are too many unknown discoveries hiding in people's attics anymore.
Plus I couldn't look someone in the eye an offer than $20 for a $1000.00 dollar coin. Its just not in me. If it was worth a $1000.00 I would have a guilty conscience offering them $980.00. Although I've tried selling some nice PCGS slab coins to Heritage, they have no problem offering some discount to Blue Sheet. They try and fund their complete retirement on each trade. Assholes.
Companies like Heritage and Blanchard have HUGE mark-ups to cover overhead and salesman commissions. I never do business with them and prefer to establish relationships with the smaller, less "corporate" coin dealers on the internet and at shows. I can name some that I like very much if you are interested.
