Quoted from Murphdom:That’s a deal then. If you were to break it down with inflation it cost about 5 cents USD per game. At that time in the US quarters were already being jammed into machines.
At the start of 1980 the exchange rate was AUD$1 = USD$1.1, so a game on that pin cost the equivalent of 22 US cents (assuming it only required one coin for a credit).
