Is This UK #128 To Be The Exact?

I am color blind...

Yes. It is the 1d scarlet stamp. There seems to have been a perfin attempt but I cannot read it except for the "& Co". Normally worth around 10 pence for a good used stamp.

Thanks how about the one without watermarks?

There are no stamps without watermarks in this issue printed by De la Rue. If you look hard enough you will eventually see a crown watermark.

Thanks again....Iam a learner and new to all this how about 128f is not watermarked on scott cat.

No unwatermarked KEvii one penny stamp is listed in Stanley Gibbons. If you can post the exact phrase used in Scott that I may be able to help. There are INVERTED watermark ones but no UNwatermarked ones

I added the screen shot above from 2009 scott Cat.

Scott Classic lists several more subtypes, including sub f as a 2011 Harrison printing with no watermark. The only similar design I see in SG is the brick red Harrison in perf 14.

What Scott refers to is a different stamp. The later printing by Harrison in 1911 has a no watermark variety. Your Scott#128 has no variety like that.

thanks guys.

SG272a and 128f purport to be the same stamp. One of the shortcomings of Scott's GB listings. Of course, it partly explains how Scott only needed 128 numbers to get to the end of KEVII.

As Cjd mentioned...Scott only provides a basic listing. rizzi stamp is a SG#219 De la Rue printing and is a Scott#128.
An unwatermarked stamp would be a Harrison printed SG#272 (with an (a) variety) but Scott gives it a #128f.
So apart from being from a different printer, a different perforation and a different color, Scott regards it as the same basic stamp

The PERFIN looks like a ' BE / &Co ' perhaps?

Puzzler if it is , what does it mean to the value of the stamp? thanks

Not sure rizzi. A UK / GB PERFIN catalogue would tell you or perhaps joining the Perfin Society online in GB and then accessing there stuff.

Yours needs a soak in clean water to remove the extra paper adhered to the back gum still, then you could see it better. Your perfin is moved up on the stamp so that would decrease it's value also, as collectors of this type of stamp would want a clear, readable perfin.

If rare, any example is valuable, especially yelling the different dies used for actual perfins and if any holes placed in error.

Interesting to collect and find out about the companies involved though.
