I recall someone researching first edition stamps and trying to determine which came first. Was that here?

Pretty sure it was on here someone had been doing a ton of research by catalogging like 1,000 first editions on ebay or something in an attempt to determine whether thick or thin stamps came first, does this sound familiar to anyone? Attempting to locate this thread. Thx in advance!

Thick/Thin is not a new thing...Proof Inside

Another thread started talking about the current interest in thick/thin 1st Ed base stamps and how thick deserved a premium. I’ve been concentrating on those stamps for 15 years. I found a decade old spreadsheet of my extras and notice how I had them separated categorized. Btw…I said extras cause I had 4 complete sets, 3 thin and 1 thick. They are still on the PSA site. Fun to see this old record below. I can remember so many stories behind some of the entries:) [image]
