Hey Again!
I do not know if it is my monitor or your scans but your colors are way out of whack.
The one you calling calling a 64 is in fact a 64b rose pink. the cancel is a dead give away. the first known use of this issue was Aug 17 1861. the 64 and 64a were not issued until December of that year. Your number 65 looks to correct, maybe a rose red. the last one you are calling a 66 is not even close to being Lake, looks more like a 65 bright red rose.
ID'ing the A25 issues is very tricky, to begin with there were 65 different colors issued. The reason for all the different colors is the pinkish colors were not very stable and are susceptible fading. Because of the fading there is now well over 100 changling shades. If you wish to see scans of the acutal stamps, just let me know and I will post them for you.
The best
Ron
