Any one know how much an original 900 series went on sale for back in the day?
Thanks in advance for your help

A IIIc went for $6,000 back in 1969 - about as much as it costs to buy a house

I have Moog modular '72 and '74 catalogs/price lists–systems as well as individual modules (although Moog Archives has the module prices). Let me know which model and I can send you a list price from those years.
According to an inflation calculator on the web, if you spent $9000.00 for something (roughly a III series with a 960 sequencer) in 1969, you’d have to shell out $55,661.58 today. If you bought a Model D in 1975 for $1495.00 (list price back then), it would be $6528.28.
Allegedly, wages and living standards have kept pace with inflation 
,
but even so, $6 kilobucks is a lot of cheeseburgers.
But nobody ever payed list price, so it is tough to calculate.
I purchased a model D in 1974, and the list back then was $1395.00, but the Moog dealer here was charging $950.00 for a new one. They always shaved quite a bit off the list price. A CS-80 listed for something like $8999.99 in 1978, but I paid $4750.00 for mine. I’m pretty sure I was quoted $4500.00 for a system 35 from the same vendor in 1978. For some reason, in the 70’s those list prices were really inflated.
The last price of the Minimoog D from Moog was $1995.
(apart from their last blowout sale towards the end.)
The reason retailers discount off list prices is that they’re probably turning product over. They’re making sales.
It’s better to sell a thousand people something and make $100 on each than it is to sell 200 people something and make $200.
Discounts are common where volume sales or quick turnover is likely.
I had many of the original Moog price lists on my site when it was up.
I will put them back up as soon as my bandwidth allotment comes down and I can upload things again.
In the meanwhile I’m sure there are some sites out there with these price lists.
CZ, Ill buy your Model D for 950. 
In Fact, You can have my Taurus III’s.
IIRC, retail dealers bought keyboards at a “B” (40%) discount–so your vendor was pretty generous with you. Most dealers usually wouldn’t budge at more than a 20% customer discount.
For some reason, in the 70’s those list prices were really inflated.
Gotta remember, this was the Carter era–inflation rates were at double-digits, and I remember mortgage rates were hovering at around 18% or so.
Just to say a big thanks to everyone for all their answers. I’m writing a small document upon Moog and was trying to get a rough figure of how expensive an original 1972-74 900 series would cost. By way of showing just how big a change things were to the potential synth buyer once the minimoog came out with it’s more affordable price. The cost of a small appartment figure for the 900 model gives one a good impression.
Crumbs I had no idea that the CS-80 was that expensive though. Glad to hear CZ Rider picked one up for nearly half the list price.
Thanks again

Here is a crappy scan of a PMI 1977 catalog. They were a mail order music store in Union City, NJ. On the average they were 25% below retail price on synthesizers. I don’t remember any of the Philly music stores that couldn’t beat their prices. It was a good guide for the times. For instance an Arp Odyssey list $1695 sold for $1270, while a Mini listed for $1795, sold for $1325. Oddys were usually about $100 less than a Mini.
Perhaps this was an east coast thing?

Thanks for that !

Here are scans from the '74 price list:
This directory below hasn’t yet been “massaged” to have the correct HTML and all, but here’s some price lists that were just uploaded from my old site.
Sure there’s enough there to keep you busy… 
I remember looking to buy a Stratocaster or Les Paul in 1976. The Strat was about $550 and the Les Paul was about $650 (only USA versions were available then). So you can also compare to the current values of American-made Fenders and Gibsons.
The Minimoog was about 3x more, the modulars were about 8 or 10 times more than a Les Paul. Pretty much NO ONE sold modulars in stores, ever! They were almost always a custom order from the factory, and specially built each time, so discounts were not offered.
$3899 is the current Les Paul price range (Strats vary widely due to model and origin, and are generally much less). $16-1800 for a USA Strat now.
My parents bought their first house in 1970. It was considerably more than $6,000; $28,000 was the figure I believe they spent on a three bedroom, two bathroom fully detached. The average new car in 1969 was about $3,000, so the six grand figure for a Moog Modular still wasn’t peanuts though.
