GREAT PIECE AND GREAT DISPLAY!!!!
i own an unlce henry 95th myself. but your knife is far superior.
i love to display my knives ...SOMETIMES...then i clean them up and put them safely away.
now this is just my opinion,everybody has one
with that said... displaying knives is fun.i love making displays and setting them up.
also knives with their diplay intact are worth more.
but displaying and storing are two different things.
i have a friedn who onws about 10000$ in yellowhorse.all his knives have been in display cases since hebought them.nice
tall beautful glass cases with lighting and everything. 3 cases full.i asked him one day about 6 months ago
when i got into restoring knives if he was worried about pitting and patina and such. he said "whats that"
long story short every piece in his collection has faded wood on one side ,little pits here and their,etcetc.
i am now cleaning anything i can on them for him.so the bonus is at any given point i have a roll of 10-20 yellowhorse pieces in a knife roll for me to play with

im making a picture library as well!!
MY POINT...
if you want to keep the value of that knife and it doesnt look like your gonna use it and this is just my
IMO i would not store it with the blades open like that.your putting stress on the springs all day every day.
plus even in that container you will eventually get patina,pitting etc etc..
my 95th uncle henry i snagged in the box for 30$- so my guess for ebay value 40-60$.
book value about 90-100$
the word mint is tough. alot of collectors i know MINT doesnt exist. "almost brand new" seems to be the choice word.see just the handling marks from opening the blades that would disqualify it as mint to alot of folks.
i have knives sealed in packages from the 60s. i wouldnt call them mint. mint is a tough word.
like the word rare. theirs a difference bewteen "rare and "rarely scene"
ok ramblin.... hope i was helpful
