Browsing through eBay
, I'm noticing some unlikely precancels. The precancel itself appears to be valid on these stamps, but not used on the issue it appears. For example, there is this one:https://www.ebay.com/itm/WASHINGTON...L:rk:30:pf:0
Someone who is up-to-date on the precancel regulations, please let me know what is going on with this type of precancel use.
I'm no novice when it comes to precancels, and I fully understand the concept of favor precancels. I was under the impression, though, that precancels - as valid items in the postal system - have gone the way of airmail stamps, postage dues and the dodo bird.
Am I mistaken?
