It's amazing how many people don't really check what they think they have before they label with a number. I did get a lot of "stuff" I need, but I think I'll keep looking for copies of J8 to J14! I'm willing to trade for them!

You are correct, they cannot be the special printings.

Thanks Don - The links help a lot. I have a fairly extensive US collection, but I have not run into soft paper. At least not that I can remember. Do you happen to know of any common US stamp that was only issued on "soft porous paper"?
Sorry - no need to respond. US stamps 182 - 218 are supposed to be soft paper. I have most of these, or at least I thought I did. After checking them out I'm not so sure. I've never understood the difference before. I bought several of these stamps from various sources and didn't question the sellers - maybe I should have!!!

A trick I learned once was to hold the stamp one edge with your (clean) fingers and flick it with a forefinger. If it "store was a distinct difference in the sound the feel. Sorry, I can't recall which stamps I was trying to identify.

I had the same thought that Bob did. I have done this many times in my quest to complete a collection of Banknote officials. (No I do not have O94 or O103 yet!)
Hold the stamp firmly between your thumb and forefinger, near one of the short edges. With the forefinger of your other hand, bend the stamp and then let it slip past the tip of your finger. 'Hard' paper will make a sharp sound as it slips past your finger - a kind of high-pitched "Doink!" 'Soft' paper will make a much more muted sound, if any.
In my experience, many sellers cannot distinguish between hard and soft paper, and will often list items as the more valuable of the two, I guess presuming that the buyer cannot distinguish either.

The 'snap' test is described in both the links posted above. It is the least reliable method for the inexperienced hobbyist but works well after you have handled a lot of Banknotes.
The easiest method is the backlight the stamp, next easiest method is to examine the perf tips. One of the most reliable methods is to use an ultraviolet light but hobbyists often do not have one and/or are not experienced in using one.

I recently bought an interesting US BOB selection on line. There were lots of stamps I didn't have - proprietary, hunting permit, documentary, etc. It was a great lot and seemed to be labeled properly, but I did check! Then I came to the postage dues - he had used copies of J8 and J9!!!! You would only understand my surprise if you collect US BOB. I think I will go back and double check everything! Two problems, they don't exist used and the price would be about $50 000! Does anyone know how to recognize "soft porous paper"?
