Hey Adam:
The bass is worth what you were willing to pay for it, like anything else you have. I paid too much for mine, but it plays so well, it is worth what I paid. So I am obviously happy I got 'taken' anyway. The last 20th I saw on eBay was really in bad shape, and it went for @ $2,000, amazingly. If you paid less than $2,000, good for you. If you paid more, like I said, it is worth what you were willing to pay. Most Series I basses on eBay go for between $2,200 and #2,800. They are quite a bit higher on music store sites. There were only 200 Anniversaries made, so who knows what they are worth? Sounds like you are happy with your new bass, and that is all that really counts.
