I also have been using the glass411.info database quite a bit recently. I find it to be very helpful in identifying glasses and variations.
Could we, the glass collecting community, enhance that database to include market values? We are always finding, buying, and selling glasses. We should consider a way to allow members of the PGCA to post real transaction data to the database and from that information derive a current market value.
Has this been considered? Has it been rejected for one reason or another? Just curious because there is such a great start in building a database there.
