I was wanting to list this group on
ebay just now and I paused when I saw the orange shade of the 30pf alongside the yellow 25pf.

Here is the stamp in question alongside one with the yellow shade.

The overprint is shifted upward slightly, but the bar is still clearly visible. Scott does not list the orange and black on orange variety as a Type II, only as a I & III, both with high CV. So basically, the control bar is irrelevant to the value it appears. Just needs to be the correct shade. To me, the background on the 25pf is clearly yellow and on the 30pf clearly orange.
I was going to list these low, but I want to ask here first before I decide on a price.
