Just picked up a can of this tobacco, and have a few questions. Wondering if there was any way to date the manufacturing date of this tin? There is a sticker on the bottom with some numbers. wondering if there was a way to date the manufacturing of this tobacco by the number? Not a big deal just curious. Also it looks like the top of the tin sealed by foil, never came across this style yet and just wondering on his quality when it comes to long-term storage? Can it hold up, I'm not too worried about this tin as I'll probably be smoking it the next 6 months but if it's one I really like and decide to celler some should I leave it in the 10 or transfer it to jars?
