Overprints (on the face of stamps) and underprints (on the back of stamps) were applied by firms to their own stocks of stamps to protect themselves against petty pilfering by their employees. They were a precursor to #perfins and used mostly in the UK and their colonies.

Thanks to Michael Cortese and Charles Epting for chatting with me about #precancels on their excellent Podcast "Conversations with Philatelists"! Enjoyed the conversation and looking forward to another on #Perfins someday soon. You can find it here: https://t.co/R0GvTABSrE

The 1st US #precancel is older than US postage stamps! The Hale & Co Independent Mail Company precanceled their local carrier adhesive stamps from 1843-45. It was done in 6 different towns and is considered a silent #precancel.

For nearly 35 years the Bureau of Engraving used the Stickney "Wet" Press for all Bureau #Precancels. Then in June 1957, the 1st "Dry" Printed Bureaus were produced on the Huck-Cottrell web printing press. The Dry on the right is sharper due to the lower moisture in the paper.

Nearly all of the ~9400 Bureau Precancels are on very inexpensive stamps, and most are not expensive themselves. This Fort Lauderdale, FL 804-73 is cataloged at $100 and available in my #HipStamp Bureau #Precancel store! (see link in profile)

Using the PSS Bureau Precancel Catalog Database, I determined today that this is the only Liberty Series Bureau Precancel (1045-81) above 2c that uses the 2 letter state abbreviation which was used after May 1965. Most were Prominent American Issues.

@defenderium I think it is the latter

US Postal Stationary was precanceled during manufacture at the envelope factory from 1928-1965. It is very common to find unlisted varieties since one could order a box of 500 and most were not saved. #precancel

Netherlands has roller #precancels with City/Year within circles. Used on bulk rate printed matter. Found one with a #perfin, making it a very scarce #preper.

Interesting electroplate repair Local type 204 #precancel from Fremont, NE. Probably the 100 subject plate was damaged at some point, and the upper right subject was replaced causing a fun variety to find. On this plate there are actually 2 repairs! #philately #stamps
