I posted about the complete strips of 4 of the $500 Alexander Hamilton back in 2018:
https://goscf.com/t/60609At that time I had 2 complete strips of 4, both Scott #RC20.
In the intervening 7 years I have found zero other examples... until 2 weeks ago.
The strip below showed up on
ebay, not described as having a double transfer, so I laid in wait and sniped. It's punch canceled (beggars can't be choosers), but this one is Scott #R249, so it's a strip I didn't already have, although I have numerous examples of single stamps with double transfers.
Complete strips with DTs are FAR more scarce than catalogue values imply.
I maintain a census of the $500 Hamilton double transfers in all its forms (Scott #R249, R249a, R285, R285a, R285b, RC20, RC20a, RD23, RD23a, RD65, RD65a, RG22) which can be found here:
