There were way more than 2,000 Striker's. There were 500 Shrek's. Most of them sold to CeC's. Your other numbers look better, but there are over 85 NBA's. Serials indicate that there should be around 200 NBA's. Stern usually ran at LEAST 200 of every single production title. Even the ones that sucked.

Keep in mind that not only people in the US buy Stern pinball machines. 50% of sales are other countries.

Saw Steelers NFL pin at an auction here in Cincy last year. Reserve was like 3K and it did not sell. Only one I have ever seen for sale.

You are wrong. It was 900-1000.

There are CERTAINLY fewer of those "Standard" Batmans than the NFL pins. 48 I believe...

Serials on http://www.ipsnd.net/ support that between 500 and 600 CSI's were made. Some were sent overseas to other countries. CSI is a worldwide show, broadcast in many different languages.

Keep in mind that:
in the summer of 2012, CSI was the MOST WATCHED TV SHOW IN THE WORLD.

Nope, there are around 400 reg Elvis machines and 500 gold Elvis machines. 900 total.

I agree. What was the "break even" to even profit dollar number 1 on these Stern titles? I know that it depends on the cost of the license and also parts and labor/insurance, but I would gamble that 0 profit was made on any games that had runs of less than 400. Maybe 370 was the break even on NBA and Stern just decided to limit their losses at that point and move on to a title that would sell better.

Non commercial product. Home model. I have only seen and played one in my entire life at Sam's Club. If you count it as a actual release, there are very likely over 100 of them. More than standard Batman.

Maybe you can elaborate on the serial numbers posted then? It seems a run of 2000 could have been overlooked on ipsnd.net on Elvis. That may account for a large chunk of the miscalculation. Specifically, 186086 to
188058
Indicates a run of at least 2000.

Why would you need sales information to determine how many games were made? That's like saying you need a wrist-watch to know the time.

@pinmaster:
If you primarily look at "internet and local sales" for your estimates, there will often be duplicate machines sold. While I appreciate sharing of personal experience with how often you are encountering machines, limiting your assessment to only that, is a far less accurate way to get a real estimate on machines that are actually out there. What about the 50% of all the Stern machines (ever made) that are not currently in the US?
