Guy on the local craigslist posted a bunch of snares, and I believe one is a vintage 5x14" Supra. It's got some pitting by his description, but he calls it a "Keystone Badge Ludwig." It's clearly got Imperial lugs. He's asking $150.
I'd say yes, even with some pitting. My near-immaculate 6.5 Supra (B/O badge from 1979) cost me $450. A 5x14 would fetch a little less. $150 is a steal - sometimes Acrolites goes for much more than that too.
A keystone badge supra could mean a very wide range of dums,from the 60's to 1970.,then from 85 till present day.Condition is everything,as supras are known for "supra acne" type pitting.Originality also plays a role,so extra holes and non-original hardware will also devalue a drum.
As Steve B said, 'keystone badge' still leaves a lot unknown. The drum is probably worth no less than $150, unless its in poorer shape than stated. If its a 1980's-2000 keystone badge model with pitting, then that's about what its worth. Its probably no newer than 2000 if its pitted, so its probably not a real recent keystone badge model. If its a 1960's keystone in good shape, its probably worth $250 +/-. If it would happen to have a chrome over brass shell, it could be worth more, but I don't think it would be pitted with a brass shell.
Just remember this: there are always tons of these for sale. Don't feel like this is the one you have to buy. If you look at it, and are not sure, then pass. There's another one to buy. I have bought and sold a few of these over the years. I bought one a couple of years ago on CL for $100. It was a 1980's keystone that the guy used for teaching. He's now running a pizza shop and just wanted to get rid of it. It has zero pitting. It just needed some clean-up. I also changed the heads, snare and strainer (my preferences) and I have really nice Supra.
Thanks for all of the input, folks. The guy never emailed me back so I didn't stress it. I've already got a 6.5 Supra, so it'd be for vanity to get a 5. I won't sweat it because I also like the dryness of Acros and I can pick one of those up if I ever want to. They're everywhere!
