Typeset Stamp - Anyone Know Anything About These?

I picked up a 'novelty' item in an antique shop today. It's a metal typeset of a 1961 Russian stamp that was used in the printing a newspaper philately column.

I've attached a photo (sorry for the quality). At top is the typeset metal template and the bottom shows an imprint that was included with the typeset piece. I am wondering if anyone on this forum can tell anything about this item.

The shop had a few more but I got the one. Of course, if someone here tells me they are valuable, I'll be returning to pick up some more.

Thanks!

It is a die made for printing in a magazine, complete with perforations.

Some years ago Amos Press, publisher of the Scott catalog, decided to de-acquisition their accumulation of dies depicting various stamps. Sales were mediocre in part because the buyer had no choice in what stamp they received. Eventually they were used as giveaways when someone from Scott catalog gave a presentation. I received several at one of the APS Summer Seminar dinners when the then current editor spoke. Interesting items and they were still covered in ink.

Here is one of the presentation boxes containing 2 solid metal cuts from the Scott catalogs. Interesting, but nominal value.

Or more dangerous: these four blocks are from the May 1970 issue of the Chronicle of the US Philatelic Classics Society.
