While cataloging & placing in my album these issues I saw a differentiation between the 3k Strip & the 10K strip I received.
The 3K Strip when looking at the red & pink flowers of either 5664/5665, the flower edge shows clean from the flower edge to the background field.
The 10K Strip shows a definitive WHITE border around these flowers on both issues. If this is verified would Scott issue a sub# or alpha designation??
I took a second look at the issues I placed in the album. The 3K is without border on all stamps on PNC of 5. However, when looking at the 10K PNC-5, the border seems less pronounced and is indeterminate on the stamps to the left of the PN.
So this is then maybe a 'color shift' ??? (Just when I thought I had something big.


After further eye strain I think it is a color shift, more prominent on the 10K than the 3K. I looked at the strips (both 3K&10K) and I found a 'small hint' of a border on some of the 3K strip. Need a glass to see it. On the 10K the glass is not needed in most cases.
Edited by RB to correct.
