Some of the first nice basses I bought were Tobias'. I ordered a Signature fretted 6 around 1992 and I think I paid around $5,500 for it (before tax!

). I later found an identical zebra fretless Signature 6 at Corner Music in Nashville and I snatched it up. I think I paid around $2,200 for it! They were a happy couple for a few years before I sold them both. I really wish I still had them.
In 2003 I bought a Fodera Edward 6 used. I got it at a NYC music store and it was marked up quite a bit when I first saw it. They were asking $7,000! I came back a few times and kept trying to negotiate the price down. Since it was a consignment piece, they wouldn't budge much on the price. I'm not sure what it's real value is today but Joey tells me it's one of the only solid-color basses and one of only a handful of Edward models they ever produced. They didn't give me a ballpark of what it was worth though, no doubt fearing they would upset me after hearing how much I paid for it!
AFA my double bass goes, I bought it from KC Strings back in 1998. It's not a full-fledged Anton Krutz bass ($14K+) but rather a sort of shop bass that was intended as a lower-cost alternative to their flagship models. I was a loyal customer of theirs and had bought and sold several basses through them. They always offered me full-value on my trade-ins so I was able to trade in my German bass ($3,500) towards their "shop" bass which was about $7,500. David Gage, one of Anton Krutz' former employers, had a look at the bass last year and told me he could easily get $14K for it! I was surprised to say the least. So I guess my DB has nearly doubled in value, something that can't be said for my electric basses.
Even though it's not bass-related, I also own a Summit Artist model F5 mandolin made by Paul Schneider. He finished mine in 1999 and I paid nearly $6K for it. I don't think it's appreciating but that doesn't matter to me since I'm never going to sell it.
