"First is one that is not a cancel, but rather a provisional 'STOCK TRANSFER' overprint. Not listed in Scott, but known to collectors."
The basic (parent stamp is R232 Documentary issued in 1917.
The stamp in the image is dated 4 Feb 1919! There wasn't any need for any provisional stock transfer stamps dated in 1919, as starting in 1918 there was a stock transfer stamps issued and used!
I've been a revenue collector for almost 60 years now, I've never seen a "PROVISONAL STOCK TRANSFER" such as this and suggest it is not a provisional, but some sort of a cancel on a documentary stamp. I've seen many provisional stock transfer stamps, all were hand written stock transfer.
I'd like to know what other long time collector think about this stamp.
I have seen this handstamp around for several years; it's not a cancel. I have seen mint OG examples of all the values under $1 with this handstamp. It is a potential provisional usage. It's possible that someone needed some stock transfer stamps on the spur of the moment and created these, although I am not at all convinced that they are genuine. They might have been created in 1918 by someone who only used them occasionally and so had a supply that lasted until Feb of 1919. As stated before, I would need to see an example tied on a proper document to accept them as genuine.
Could it just be that they had a surplus of old stamps to use up before they used the, by then issued and referred to Stock transfer stamp? Just a thought. Revenue collector those are absolutely striking and I always enjoy your posts! That Cornelius Vanderbilt one is amazing to me! Thank you.
I sent the image in question to Richard Friedberg, and his opinion meshes with Bart's opinion for the most part. He too has seen it on other denominations and considers it a provisional usage of a documentary as stock transfer. He believes that the reason these are not listed in Scott is that they were done by private firms, unlike the narcotic provisional handstamps, which were done by district offices.
These were not "old stamps" at the time, and the documentary taxes they were used for lasted several more decades. Either a private company used them and we have not found any documents as yet, or they were created later in an attempt to scam collectors. I think that if they were actually found used and tied to a document and got a good cert than Scott would list them, just as they do list certain narcotic stamps that were used by and for specific private companies (RJA26-29B).
