What is the value of a 2004 fender telecaster electric guitar?

60 or 70% what you paid for it , only old fenders go up in value or limited edition. Because it's not either by what you told us honestly people look at it as another guitar. Now if you hold onto it for 30 or 40 years than you'll get some return investment.

the only really valuable Guitars are iconic ones

ones where they spelled stuff wrong

very limited edition

and totally unplayed guitars with original cases that would be like jumping in a time machine to get say a 1950 fender broadcaster or whatever

if the guitar is played so what honestly , enjoy it. It's a Fender and people love Fender guitars who I deal with on a regular bases.
