The saries one seems to have a date overprint of 1848, whereas it should be 1948, not that I know anything about US revenue stamps. The cancellation reads as 194?, which should make it R502. Maybe a more specialized revenue catalogue would give a more correct answer.
You are correct it is a 502. The date is 1948. I had to take a better look since you mentioned it. Here is a better photo. There is a gap in the bottom loop of what seems to be an 8 just barely but it is there.

Looking at the Scott catalogue, they show the words/date above the listing and they are very different print characters for each year. The 1948 series shows the 9 as almost joined and the e's are quite enclosed, so it probably does read series but blobby ink and the typeface mean it blurs the letters.
Maybe a high definition scan of just that part would yield a better image, or even a microscope image.


Here is some better images with stamps of the same series and date of use. All of them likely came off of the same document but we will never know because when I came into possession of them they were already removed.
The stamp in discussion still fits the bill very nicely in EFO category and will remain so in in my collection.

The next photo includes per fins and were all in the same lot too.

An interesting fly-speck!
I would say it looks like a broken plate or something.
If any member can find a second, we can call it a variety, and submit it to Scott if you like!

Thank you Ari.
If these questions can be answered by someone more adept with revenue stamps then we'll be that much closer to determining if it is actually an error, freak or just an oddity. Now I beg the questions. How were the words series and date years placed on revenue stamps? Were they placed on them with type set like a newspaper printing press or manually with a type writer in some cases or part of the plating process?

Here are some more revenue stamps that came out of the same lot that I found the R164 with the embossed and manuscript cancel in. After sorting through close to 800 stamps in the lot. My best swag estimates that 10% of the lot was revenue stamps and a lot of them are perfins. Which really isn't all that un-common but what is un-common was the care with which they were removed from the original documents they were affixed to. All of them are in remarkably good condition which has made identification relatively easy.
It has been my experience that revenue stamps are treated by most collectors with a great bit of neglect and distain. But there are those who revere them and go through great efforts to save them from making it to the land fill. This had been the case with whom ever originally owned them especially to the care given to the perfins in this lot.
Early in my collecting years not much thought was given to making any real effort to collect them and I can honestly say that was because I was taught to seek out the trendy fashionable commemoratives, air mails, definitives in MNH condition and all of the popular fodder of the day and honestly I didn't understand why because the 19th century U.S. revenue stamps are in my opinion some of the most colorful and beautiful stamps every created.
In the image below the stamp on the left in the middle looks like it has had a fugitive ink transfer to me. What says you experts?
Fly speakers eat your hearts out with this stamp. It looks like an error to me. The word series is mis-spelled and spells sarles instead.
