Really glad I've discovered your site and have been enjoying viewing the galleries of vintage cans from all over the world! However one thing I would like to know and it's been a head scratcher from day one of my can collecting. Is a can significantly worth more unopened rather than opened? I don't want to stumble into a valuable can ( always the temptation to open the thing and discover how it's contents have fared through the ages! ) open it. But then decrease its value.
So if you one of you fellow souls could help a newbie, that'll be much appreciated.
Hello and welcome to the board! You'll probably get various opinions on the question you asked about opened vs unopened. Here's mine - overall condition of the can far outweighs it being "unopened". I do however, "bottom open" cans whenever possible, just in case another collector considers the unmolested top a plus.
I never keep cans full of liquid! Once you have a can spring a leak and slowly drip down over other cans, you'll know why. No one can tell if a can is full or empty on a shelf.
