I guess I see both sides of it. Too many times I have seen people rush to an Internet site in an attempt to find out the value of their find. Not for the purpose of understanding what they have, but how much money they can make from it. I would just as soon that this sight did not become an appraisal for hire sight. If that is your reason, check completed auctions on eBay on like items.
I know too that when you do come across a special deal, you really want to understand what you have. In that respect a place to come and discuss these things is a special place.
I can attest to the fact that Cameron was not attempting to see how much money he could make, off his file, rather trying to find an appropriate place for it to go, where it can be appreciated.
So, how can we accomplish a proper exchange of information without it becoming commercial?
