Bally 742A-M186  
Hi Roger. I am trying to find the value of a slot machine I have. The tag shows 742A-M186, then 8223, serial #154848. It is a Bally Chicago machine by International Game Technology.  It is a 3 coin 25˘ triple 7 machine. I think a grade 4 would be justified with no bad metal or wood cabinet on it. It is fully functional. The only problem per se is the tag is blank for the manufacture date. Someone with supposed knowledge told me it was worth $1200. I cannot find a comparable on the web to get an idea.  An acquaintance wants to buy it and I want to give him some slightly discounted fair price and not worried about max value. I bought it from someone who needed cash for $400. Time to clean out the house so it has to go. Attached is a pic with a quick cropping job so please forgive that part. Thank you in advance! Tim

Hi Tim,

I hate to be the one to have to tell you this, but this is no model 742-A, the 742-A came out in 1964 and was a lot smaller machine all around, and was an electro/mechanical slot machine. This is a Bally series "E" for electronic slot machine, meaning it has circuit boards in it which the Bally 742-A did not. This I am sure is a Bally Series "E" Model E-2090 I believe and made in or around 1983. It could be that someone switched the model number tag on it and sold it as a 1964 machine instead of the 1983 machine that it is. Value is hard to guess, there is not really a blue book to go buy. If I were going to be selling it I would guess it would sell from a low of day $400.00 to a high of around $1,000.00 and I would be fine with taking say 6 to 7 hundred for it and by selling it in a non retail way. Like on crags list or through a want add or even on consignment. I hope this will answer most of you questions about this machine and if not, please let me know what else I could do to help you. If you need a manual or manuals for this machine or even the Model 742-A you can find them at the web site below.

Thank You

I am an expert on old coin operated machines, slot machines, trade stimulator's, jukeboxes, old arcade machines, etc. I have been identifying these for people who respond to my web site listed below, for a few years now. In almost all cases I am able to tell them about their old coin operated machines, the year, the value, and other general information about their machines. I do not know much about soda vending machines, coin banks, or scales, but I will try to help you with these if I can. Please email photo's to: My web site is at:


I bought my first slot machine, a .50 Cent Mills Black Cherry in 1969 and have been hooked from that time, I still have that Slot machine! Before that I found a open barrel full of old scraped jukebox wall boxes behind a restaurant, I wanted them all but never took a one of them. Anything that took a coin drove me nuts!

C.O.C.A. and other slot and coin operated machine groups, associations, groups, and clubs.

Many, the Coinslot magazine, always juken, Coin Slot Journal, Slot Box Collector, and others that I don’t remember at this time.

Graduated from Ballard High School in 1969, went to Edison Technical Collage for a couple of years taking welding and metal fabrication, tig, mig, heliarc, also arc and gas welding and fabrication. Then Apprenticed under a slot machine technician who worked in the slot machine industry Reno Nevada, and set up bar poker progressive machines in the casino's, and repaired machine and did the repairs on slot machine circuit boards there. He also was involved in the 2 hand dealer's market and bought and sold machines at the casinos auctions for the secondary market, which includes selling used machine overseas. I learned a ton from this man; he always had the correct answers and took the time to teach me the business. My interest and knowledge in other and older coin operated machine is for the most part, self-taught. It's been my passion from back in 1968 and before, my thirst for knowledge about these machines has kept me more interested over the years, and keeps me searching for more information even today. I have meet and talked to book authors on these machines, attended hundreds of coin operated shows and auctions, and I stay with that to this very day.

Awards and Honors
Take a look at my allexperts rating, and my guest book, links to these are at Also you can check my 100 percent rating on ebay, as I have been there with ebay from their day one, I am user coinslots at ebay. My other awards come from the very people that I deal with, I always make them happy, no matter what it takes, but they always are happy anyway as the countless thank you letters testify to me, so I know I am doing right, and the best I can. I have found so many hard to find parts for people, I hunt them down and don't stop until I find what is needed to get that customers machine running again and back to life, that is my main goal.
