David AtkatzThat's absolutely true. I've been collecting vintage (1920s and earlier) Yankee material for more than forty years.
I've made mistakes, and so has PSA, Jimmy Spence, Mike Gutierez, and the rest of the "good" authenticators. I've corrected those I've mentioned a time or two--and they've acknowledged their mistakes--and I've been corrected by one or another a time or two.
But the bottom line, at least for me, is that I've got the experience to trust myself rather than a third party. And It's taken many years and a lot of work to get there.
