Recently won this collection of CSA stamps and I'm pretty thrilled about it.
I saw in the sellers image one obvious forgery, what Dietz calls 'toothless old man'. Since I also collect forgeries, I' was very interested.
Arrived yesterday.

#2, #4 stone 2, #7 Richmond printing on local paper, #8
three #11 (one early Archer & Dale printing and two later Keatinge & Ball, #12 Keatinge & Ball printing
On the bottom row, #14 unissued, 3 New York forgeries and a #11 forgery referred to in Dietz as 'toothless old man'

I found the grouping also included 3 New York forgeries. These were created by altering the 10˘ Altered plate, and can be discerned by the short horizontal middle strokes on the F and E in FIVE, and also, I've notice in all I've ever seen a small dot to the upper right of the upper left six pointed star. Also, according to Kimbrough, the #11 was never printed in this green colour.
Part of my Christmas bonus well spent!
