I was young at the time - But what you see here WAS typical of weekly earnings in "the good old days".
I remember the days when the old man would get service calls only to find the reason the machine was not working was because the coin box was overflowing.
Machines were emptied weekly in the 70's - the coin boxes were too heavy to lift out of the (good) machines.
Thanks for sharing, Marco - cool piece of history you have there.
