Color Shift?

What degree of color shift has to occur before it is considered a plus to a stamp's value instead of a detriment? Back in 1991 when it first came out, I got a roll of the F Tulip stamps that had a reasonably noticeable color shift. Sorry about the poor quality of the image, I don't have proper photographic equipment so I thru this on my old flatbed scanner.

Thanks.

Here is a similar strip on ebay for $40

Very nice, your's is actually better than the one shown on the ebay link that oldguy was kind to have shown to you.

Your's a strip of 5 with the plate number.

Nice find.

Ernie11, that is a nice PS5, ( plate strip of 5 ). Yours has enough of a color shift to fetch a nice couple of dollars, but please do not quit your job yet. The strip on E-Bay is nice, but overpriced. Usually this sort of thing will fetch around %15.00 if you can find someone to buy it!
By the way, the E-Bay strip is not a plate strip, just two strips of 2. If you read these forum threads long enough you will find out that Bill Langs is extremely proud of his wares!

I would certainly pay $15 for this one.

Thanks for all the feedback. Back in that time I was collecting PS5's. In this case, too late I separated the PS5's from the roll before I discovered the color shift.

Ernie, you still have a good plate strip or two! The whole roll may have brought more than the individual strips, but one never knows! When I quoted $15.00 per PS5 I was just going by what varieties usually go for; this one may be worth more ( but not the 40 dollars for two strips of 2! ).

I still have the rest of the roll, too. I caught on to the color shift before I used any of the roll for postage, so I saved it. I was just sad that I had removed the PS5 from the roll before I saw the shift.

Was this coil, every 30th stamp having the PN or is it every 27th?

Just curious.

Every 24
