It simply designates that the car was registered in Queensland, Australia. The first plate ever issued by the Main Roads Dept in Queensland was back in 1921, and they numbered each plate beginning with the letter Q until they eventually hit 6 figures, then changed to the current style of 3 letters and 3 numbers.
There was an auction held back in 1985, and a total of 142 lots were auctioned. The plates have proven to be a solid investment. Q23 (the plate I mentioned was for sale for $50K) sold at that auction for $3700. Other prices that day....
Q1 $100K
Q2 $31K
Q3 $15K
Q4 $13K
Q5 $13K etc
Any single digit plate is worth well over $100K now.
The high-rolling gamblers and die-hard numerologists seem to love mine
