I have an old Peugeot 12-speed in excellent condition (needs new tires), and would like to sell it. However, I have no idea what it's approximate worth is. It's probably early 80's vintage; the paint job is red, with blue lettering. I didn't notice a model number, probably because I don't know where to look. The bike has always been kept inside, has no rust or rot, and was never really ridden all that much. In fact, not at all in the past 10 years or so. If anyone could at least give me a realistic range, I'd sure appreciate it.

Look on your bottom bracket shell. There should be a serial number there. Some info on reading serial numbers is here:

Scroll down a bit and you'll find the info. Here are some old Peugeot catalogs:

Value can range drastically, according to the model. A nice late sixties early seventies PX10 can be worth around 500$ (more if parted, but that's another story altogether). A hi-end Peugeot from the eighties, maybe 200$ on a good day. Most Peugeots are more pedestrian in value, and are worth 25$- 35$, though they can be found for less. I hesitate to attempt to even figure out what model you have without seeing it, as I've consistently been a poor guesser on such things.

I agree with my fellow Peugeot PKN-10 owner, but observe that a 1963 PX-10 did sell for over $7000 on eBay. There is also a huge value difference between the PX-10 and the PR-10/PKN-10, even though the only differences are the Reynolds 531 stays and forks and chroming of the stays.

What size is the bike? I'm looking for something for my brother to ride brevets on.

Hey, you have any pics?

And listen to Poguemahone, he knows what he's talking about.

I really appreciate the quick and informative responses. I turned the bike over, and tried to read a serial #, and there is one stamped into the metal where the pedals are installed (is that the lower bracket? Please excuse my ignorance). I really couldn't make out much - there are 6 characters: the first two look like 55, I can't make out the second 2, and the last 2 look like 24. I'll try to drag it outside and see if it's any clearer. I'll also try to take a few pics - it really is in nice condition.

Unless these bikes suddenly surged in value at some point, it's probably not a real rare or valuable one - I certainly didn't pay all that much for it when I bought it, secondhand, from a bike shop in Miami. But I've changed nothing on the bike - all the components are original, and in good condition. Someone asked about size - I think it's a 26", but I'd have to measure to be sure.

If I can find any more significant markings on it, I'll post them. Thanks again to everyone.

Well, I wasn't going to explore this any farther until the weekend, but now my curiosity is piqued. After examining the serial number outside, I'm pretty sure the middle two digits are 86 - so the full serial is (I think), 558624. There is also a decal on the downtube (the one the seatpost fits into) that says, "Double butted tubing - High Manganese density". I've take a couple of photos, and would be glad to email them to anyone interested. They're a bit too big to post here.

Well you can always attach them to your next message. I think its the moutain icon.

I confess I'm somewhat lost. I'd like to see the bike; you might take a look at the catalogue link I gave and see if anything matches up. Even seeing it, I have no idea if I'd be able to identify it; my post 1980 Peugeot knowledge is limited, most of what I know is within the timeframe of my Peugeots (roughly 1967-80). Frankly, any double butted steel frame is worth something; probably a little more if it's lugged, but still worth something. Double butting generally indicates a middle-to-hi end bike.
