Just picked up a small collection of revenues with these items:



Though not terribly expensive, just not something you come across every day.
As a bonus, the R191a and RD11a are not cut, as is common with a lot of these issues. In addition, the overprint on the RD11a has a distinct orange color (I think). Can anyone verify if they have copies of RD11 or RD11a if the overprint is definitely red or an orange hue?
The RI14 is very scarce used.
