Old Bernina Machine value
 

Help me please find out where I can see the value of my 3 Bernina's. #830 record-#800, #810. All in 'as new condition.
Thank you in advance. I appreciate your valuable time.

Visiting a dealer would be a good place to start. Or see if there is an appraiser near you. ( Value) has many factors.... Market value is Dependant on location, availability, popularity, many factors. Insurance value is determined by the possibility of needing to replace. There are lots of factors.
You can research to see what other people are ( trying) to sell them for, and what they actually sell them for ( eBay, dealers...) If that is what you are trying to determine. Location always matters in resale value- what sells for $50 in one area may be $250 somewhere else.

I work at a Bernina dealership. The most we have sold a used 830 for, was $550, and it had 12 presser feet (including a walking foot), the case, knee lift, accessory box, sew table, bobbins, etc. The 800 and 810, would go for less. I fixed an 807 that I got from the thrift store, and sold it for $125. You might be able to get up to $250 for the 810 if it has lots of accessories. The thing you want to be sure of on these older Berninas is that the camstack and vertical shaft gears are not cracked. Also, make sure the stitch selector lever (on the top, right), and the needle position knob (in the center of the stitch width knob) are not gummed up -- which happens when a machine has been sitting unused for a long time.

Good Luck with selling your machines!

As quiltedshineshine stated, the amount you get for a used Bernina has a lot has to do with the physical condition of the DSM and the amount of accessories. You might watch some auctions on eBay.

Do your research. Look at closed eBay sales to get an idea. What someone sells it for in one area will have nothing to do with you.

I sold an 830 for $300 about 20 years ago, but they are worth a lot more now. People have found out what true gems they are-- all metal, inside and out, except for one small teflon gear. I've seen them on Ebay and they never seem to sell for less than $400-- sometimes up to $1000.

Wow I wish you were closer

Not all metal inside. At least 3 gears are nylon and there is plastic on the body etc that can break pretty easily. But still I own 3 of them.

I've got three 830's as well! I keep trying to decide which two to sell and which one to keep. It's impossible! They are really great sewing machines - I do FMQ (badly) on them, and they sew beautiful straight stitches - you practically don't have to hold onto the fabric! All being said, I also love my Bernina 750QE and tend to go for it first...
