There are 3 different Harley pins. The 91 Bally, the 99 Sega (and later Stern), and the 2004 Stern. The 04 Stern is regarded as the best of the lot. Also the most expensive.
Game play is weak on all. IMHO, this had enormous potential, given the Harley theme. What they actually produced was lame.
As a pinhead and Harley owner, I entertained thoughts of purchasing one of the Harley pins. I continue to play them whenever I run across them. And its always the same.
What a disappointing pin.
All three are priced about double what they actually are worth to a pinhead. Pinheads don't drive the price.....Harley owners seeking yet another accessory drive the price.
If you're a buyer 91 Bally $1200 - $1500 Sega/Stern $1600 - $2200 04 Stern $1800 - 2500
If you're a seller....don't bother listing these on any pinhead sites. List on Harley bike sale sites. Harley owners know little about things such as pin game play, but as long as the Harley name is on it, there will be demand.
