Sc#367 Lincoln Thread On Back

Could someone explain to me why there are threads on the back on this #367. It doesn't seem to be a grayish tint to it to be a #369. Is this common for this stamp? I have 3 other #367s and do not see any threads on them? You time and views are appreciated.
Thanks

Looks like another stamp was stuck onto back of this stamp threads and all.

First thing you want to do is to give the stamp a bath. If the fibers you are seeing came from a source outside the stamp itself, they should detach, leaving you a clean stamp. I've never seen any fibers on any of the stamps of that issue like you are showing.

I would be interested in knowing how the bath turns out.

Thanks redwoodrandy and Stampman2002.

These threads appear to be on the surface and should soak off.

Thanks revcollector.

Those are silk threads from what is called granite paper, which many countries in the 19th century used for their stamps, Austria for example. There appears to be some paper stuck to the back of your stamp, probably from another stamp (there appears to be a hint of perforations along it's edge) or possibly a writing paper. As already mentioned the threads and excess paper will come off with a soak.

Those marks and the threads could also be leftovers from a fancy envelope or post card, which were both in fairly frequent use at the time.

erm, ya. I guess I meant envelope when I wrote 'writing paper'. Certainly, the stamp doesn't go on the writing paper. Thanks revcollector.

I am hoping that Newby Stamper will post an image of the back after he soaks it to bring this thread full circle.

Pun intended?!

Also for those interested in seeing watermarks, the reverse P on this stamp is very clear.

Thanks again revcollector jamesw and 51studebaker Great site you have going. I'll try when I get home 8m a couple more days.
Revcollector is there any significance with the water mark on this a stamp? I know different type stamps like booklets and so forth are turned to certain position.

Not to my knowledge. They all have a DL watermark, and I assume it comes in a wide variety of positions since no one was really paying any attention to them during printing.

This stamp just makes it easy for newbies to see what a DL watermark looks like.

Thanks revcollector. It does stand out.
Thanks SCF for all the vauable info here.
