It's the only JKA dama I don't have. @htimSxelA is this the kind of thing you have to go to japan and look in ancient thrift stores to find?
Honestly this probably isn't a bad plan. I got mine from a Japanese friend who found it in a flea market in Japan, cost him like $10 in JPY and I traded him a sweet handturned Terra for it
Ha ha! I asked my nephew to keep an eye out for blue sealed jka kendamas when he and his family do boot fairs. Never heard a thing back though.
Honestly not sure, they're rare enough that I haven't seen them up for sale publicly often. Without the hype that OG mugens have (and shin saks are lower QC level for sure), I would guess somewhere in the $80-200 USD range depending on condition. If you have one fresh in package maybe more than that, but at that point your buyer's pool would be a small group of collectors, so it's hard to say.
Hmm $80... @Cheech_Sander I have one gathering dust that I maybe willing to part with. If you PM me and I can let you know about it etc.
