Greetings to all,

In an effort to document as much as possible in the hobby, I started a while back to note and record every serial number of pinball machines that have come up to my place. I STRONGLY encourage others to do as well! It is a quick thing to do and can be done here:

http://www.ipsnd.net/

The database is a great reference as to how many machines are out there. Sure, sites like Pinball Owners are great, but none really have any system in order to document serial numbers. They are mostly "collector-inventory" oriented. IPSND is more about a global surviving inventory. It is a snapshop of what machines are still out there! And it is kinda cool to see that where they are all located!

So please take a pic of your serial number and register it! Don't feel like doing it? Then send me a pic of your serial number and a brief description of the machine's condition (working, a parts machine or just an empty cab) and I will do it!

Let's see how many are out there!

Interesting site.
I recently went on there to see how many Cactus Canyon were registered and how I could determine if my build # was also matched to the serial #.

I had a faint hope of, one day, finding my missing #192 commemorative plaque.
It's probably sitting in some European landfill

What all places on a pin can the serial numbers be found?

For modern pins... back of cabinet, inside cabinet wall. On WMS there were little stickers everywhere. Under the coin coor, on every single board, etc...

Gottlieb wedgheads had them stamped into the front of the cabinet and also sometimes on a sticker on the top arch.

Not too sure about other manufacturers.

The best number I can find on my Solar fire is 540936. This number is ink stamped on the bottom of my playfield and on stickers most of my boards.

It had a production run according to the IPDB of a maximum 782 units. I can't see a pattern.

Williams always had 6-digit serial numbers.

The serial numbers don't always match up with production numbers.
For example, They wouldn't necessarily start at 540001 and there wasn't consistency from one game to another. I'm sure there were reasons for this, but I don't know what they were.
