Need Help With A 528A

Is the stamp on the right a forgery? As you can see there is a stark color difference and not from carmine to bright carmine as listed in Scott. Besides being a even brighter red than in the picture below there is a definite lack of detail, very noticeable in the vertical lines on the ribbons and hair. I've had experience in old counterfeits.

Sorry, but trying to compare two stamps not scanned into the same scan is a fool's errand.

John, I would have had I a 528A. Didn't want to put it alongside a 528B. It is a picture captured from Seigel.

Ok, Good to have all the details up front.
Color can't be compared then. Scanned directly next to other offset stamps would make for a more valid color comparison.
Evaluation of the fine detail is a matter of scan resolution.

The (2017 catalog) listed counterfeit version is perf 11.9, which yours isn't.

This is a scan of an unused and used postal forgery similar to the offset issues, from my collection

The original right hand stamp does look like a forgery. Terrible perfs.

I will break out the VT-600 and make a better scan alongside a 528B John. The color difference is quite striking - definite red versus carmine.

WTCROWE - thanks for the pics. The vertical lines in the ribbons is quite similar to mine. How would you rate the color of yours up against a legit 528?

Left stamp Postal Forgery - Right Stamp Scott 528A

A single scan of three, the questionable one in the middle, the others are of the 528 series. Sadly the scan still does not show the intensity of the red of the center stamp.

The center stamp certainly has a difference in level of detail and color.
I would not get caught up in trying to describe the color, but let the image do the talking.
Perf rate is very good match to the other 2, thus it is not the listed perf 11.9 counterfeit on that fact alone.
Might be worth certifying to get more real eyes and reference material compared to it.

There is no reason to believe that the stamp is anything other than a somewhat under inked type VI 528A. The press operator may have kept the printing on the light side to avoid the possibility of paper sticking to the blanket (transfer roller) and finding its way back to the plate and the ink roller. Paper stuck to the ink roller is difficult to remove and usually comes off in small pieces. Toning of the paper suggests that environmental color change may have occurred.

Finally, the stamp on the right is a type IV 526 rose carmine, different than the carmine shade of 528, 528A and 528B. It is easy to find rose carmine and carmine examples of 527. While Scott also lists 526 in carmine, I don't recall seeing any.

The stamp on the left appears to be a very heavily inked type V 527 which, as noted above, comes in two shades.

The questionable stamp appears to be about a perf 10.

This will help with the perf questions:

It is not perf 10
Is it a 10.9? You tell me.

Cfrphoto - you are correct, the stamp on the left is a 527 (has a plate # 11214) and the right, 526. I have (2) 528's (with plate #'s) identical in color to the 527 and a heavily inked 528B which I thought a poor comparison. The two on either side of the questionable one I felt were good enough to show it was not in the same color family.
