Research

Serial numbers between 360400>383000 were produced between 1925 & 1930. Actual value is determined on many factors which cannot be accurately estimated without a professional viewing and "hands-on" contact with the instrument do to its many working components, care and condition of the instrument and of coarse playability.

The made in China Charvel guitars are worth about $100 - $200 ?
depending on condition? they made and sold a lot of those,
unlike the USA models that are $500 - $1000 used
the New Charvels are $2000 +
it's going to be tough to find serial number information online unless you contact the company. ..

Your best way to get a correct answer is to call Jackson at 480.596.9690
Here's a link for serial numbers, but it only covers US models

Cy04. The first 2 numbers are generally the year of manufacture so yours is 2004
as for value it depends on lots of factors ie condition model etc but generally base model squires can be purchased new from as little as 100-$200.
so unless yours is something special It wouldn't be worth much.
If you think it is worth more then u need to do ur research

Mr. Name, This is not a cop-out, it is the truth: The money value of ANY guitar is only what someone is willing to pay for it. Even if it seems like the absolute coolest handcrafted thing - made from fairy-wood and carbon nano-tubes, If you don't have an offer- it's worthless. That doesn't mean it's devalued, but, That Nashville Blue-Book valuation thing is a worthless myth. As an expert in valuation, I can tell you definitively, an instruments monetary value is set by the market, not the seller.
