Hard to say, the pictures are not great references on condition.
I was at least able to see it looks like a JA500, and made in Japan.
The dates for this model look to range between the 70s and late 80s, so it's vintage.
However the prices I saw when researching were all over the place.
Ranging from about $250 USD to about 900 USD.
That said the most average price, which is what it is probably going to sell for is about 300 or 350.
You can try to list for that 900, but I can almost guarantee it wouldn't sell
Just like someone on eBay listing a beat to dirt Les Paul and thinking they would still get 15000.
