I have yet to record an example of Bally Touchdown but Bingo pins do have their place in the EM community.. Those that i do have recorded and pehaps the bulk of them are currently running between 100 - 600 and these would range from poor to good working units. Many of the Bally Bingo games do not fetch a whole lot of money but some of them do get higher up in the numbers.
There are better condition Bingo games that i have recorded for example:
The highest price paid for a "Restored" Bally Lido Bingo was 2200.
The highest price paid for a "Unrestored Excellent" Bally Golden Gate Bingo was 2400.
The lowest price paid for a Bally Show Time Bingo was 76.00 dollars.
Bally Miss America Bingo in VGC & Shopped 1500.
Bally Acapulco Bingo an Original Survivor went for 2000.
So yes, some of them can sell for good money. Its also important to note that certain themes or followings or features behind a game title can make them worth more than others.
In conclusion, the game your looking for would be worth no less than 34.92 to 76 dollars in poor/rough condtion, 100 - 300 in poor to average condition, 300 - 600 in average to good condition, 600 - 1500 in good to Very good and 1500 - 2400 in very good to excellent condition. This seems to be the pricing threshold for Bally Bingo's as of late.
