Japanese Coke bottle

Hi Bobby, I got to visit Japan the week of the USA moon landing in 1969. Of course, it was ALL foreign to me, but when I bought a 6oz Coke with Japanese writing on it, it became my own personal treasure. The bottle is in pristine shape with Japanese writing on one side, and Coca Cola on the other. What I found fascinating was back home we'd play a game to see whose bottle came from the farthest location as all 6oz bottles at the time had city names on the bottom and this bottle from Japan is blank! I know you don't price these, but do I have a bottle that is rare or hard-tofind? please advise.
