Rich,
All I had to go with pricing wise was worthpoint and the most recent auction I was able to find was in 2012 where a mcgwire went for $177. In 2008 there weren't any pre-production golds going for $10 but a few "cheap" Clemens BIN's were hit. I ran out of free searches for older listings...
Just got these gold pre-production's in. Anyone know how many gold sets are out there? I always thought there was only 1 set but it looks like onionring also has a gold version of P71.
Are you setting up at Barnyard or the one with the castle looking building? Barnyard seems empty compared to 3-4 years ago where as the castle one still looks packed when I drive by.
I missed out on a green copy last month that sold BIN before I even saw it so I was happy to be able pick up a purple copy. This is #17 :D. I can't imagine there are too many more floating around that aren't locked up in collections.
