True, everbody makes mistakes. The problem is when it continues into a trend.
When I started collecting (as with a lot of other collectors here), we did not have the luxury of the internet to vet a piece. Yes, we has soem books, but mostly relied on the honesty of fellow collectors.
Books were written and some have been identified as having bad pieces referenced a original pieces. Now, if a collector is usign those references to collect, tehn that is not helping them.
My first venture into collecting an SS dagger (before the books/internet) only brought me heartache. Fortunately, Gailen David steped forward and help me out with knowledge. Some of the "big time" collectors didn't have the time to help a new collector.
So, I guess what I am saying, regardless of the books or info available today, we should share our knowledge and help the hobby get stonger and grow, not hide our knowledge thinking that if we share, the competitors will get ahead. Ron
