I think some games perhaps hold more sentimental value than actual gameplay.
I spent many holidays as a youngster sweeping the gamesroom floor at the caravan park and doing other odd jobs for the park manager to earn those 20c coins with the black crosses on them (must have been something between the op / manager) to play the Hankin FJ Holden. I enjoyed the game play (at that time) and keep in mind for a game made circa 1979 it wasn't a terrible effort. I would certainly like to own one - mostly for the memories but also as a very Australian piece of a hobby I enjoy.
Don't worry - when we did the collections (counted the cash tin) we 'overlooked' MANY of those crossed coins - hahahah
Some 'sites' believed that if they put a 'nikko pen' cross on the 20c piece it would be returned to them - I made sure they got about 25% of them - but I'm a prick!
