1) Is there a market for TN specific state revenue stamps? eBay
is difficult to gauge, it looks like there is.
I am only aware of 1 collector who specializes in TN state revenues! That said, there are hunting and fishing collectors who collect all or many states, and some that focus on hunting tags.
Your fur tags are very, very nice! I have none in my collection (I foolishly collect the state tax stamps of all 50 states and DC).
There are many folks that collect by category, rather than state, like beer, liquor, wine, cigar, etc., and I have no doubt there will be collector interest in the TN stamps if the prices are reasonable.
2) Is the State Revenue Catalog by Dave Wrisley the definitive source? Scott's seems to mainly do US
Absolutely the most up to date general catalog for all 50 states and DC. Keep in mind there are specialist catalogs for single states that list minor varieties not found in the SRS catalog, but there is no specialist catalog for TN.
3) Is there a "best" way to preserve them if there's anything of value?
For the most part, stamps are stamps (yes - I know there are always exceptions), and any accepted safe practice for stamp collecting should be safe for state revenue stamps. NEVER use any scotch tape for anything involving stamps. Don't use hinges for better mint stamps. Be careful with heat activated "fusions" or water applied stamps (like your tobacco examples). Some of those are very fragile and just the sweat on your fingers will cause problems for some of these issues.
1,000 TN stamps is a very intriguing collection. Don't know if there are several sheets of 100 equaling over a 1,000, or if you managed to get your hands on a very specialized collection. Can you post some more scans of other pages?
There are nice issues in the early Cereal Seed, Grasses and Clovers, Oleomargarine, Ammo, etc. Almost all the tags (regardless of category) are decent.
Great collection and congrats! I sadly haven't run across a nice unpicked collection like that in years!
I suggest you go to the SRS website (link above) and risk $26 for a year and a half membership. It will be good until Dec 2018. Do it. Do it now!
