I received my first collection piece when I was 20(That was a year ago).
However, sadly enough, it was a gimei katana( wasn't really sure whether it was a tachi or a katana).
Frankly I wasn't surprised to hear that there is a great shortage of young collectors.
Well, it does cost a fortune in the end doesn't it? It's hard to see young people who can afford such luxuries.
Cheers,
Aris
