Here is my 1914 T330 Piedmont Art Stamp...I don't think any Cobb has been graded higher...it has a Factory 42 back...it was already graded by SGC when I bought this in 2005 in a catalog auction...since I had not seen another in such high grade I was curious to see what a PSA 5 Cobb stamp would bring 15 years later in a 2020 catalog auction... I think it had a Factory 25 back...so I followed the auction and was pleasantly shocked to learn that the high bid was $21,000 but was $25,200 including the 20% buyers premium...but even that price was before sales tax (which is 3-7% except for a few states that have no sales tax), or shipping, handling and insurance...so the total paid was very likely $26,000-27,000!!...and I felt I may have paid too much for mine when I wrote a check on my home equity line of credit for it...it was a major purchase for me at that time as I could certainly count on both hands the hobby items I had ever bought in excess of $1,000...times sure have changed.
