Precancel collector. I started collecting US precancels of almost all sorts about 18 years ago, and joined here a bit later. Bought many job lots and state lots on Ebay, found a few rarities
and gradually have been wading through the rest.
I also collect UK and US used (since 1966 and 2005, respectively), but those are on hold until I slim down the precancels I haven't sorted yet.
Due to inter-state house moves, endless house repairs and renovations, and supporting my kids into adulthood, I haven't had the chance to work on my collection for more than a few weeks (in total!) since 2016. But life has calmed down and I am back at the beloved grindstone, with fingers firmly crossed that life will cooperate for a good long time.
