Hi Johnny,
yes I'd agree it was a 1963
Epiphone Olympic - but with few original parts - the tuning keys, control knob and bridge are replacements - the scratchplate may be original, but has had a hole drilled for the coil tap switch - which in turn suggests the pickup is not original - but I can't say that with 100% certainty. Has there been any extra routing under the scratchplate?
Has there been a headstock or heel repair?
Are these photos just dark (ie is the finish a sunburst) or has it been painted black? The serial number looks a little 'odd' - as if this guitar been refinished and the numbers restamped? To me, from these pics it looks refinished. In a sale situation, you should clarify this with many more pictures taken outside in good daylight. Have a look at this article
how to sell a vintage guitar online
This has the typical Epiphone shaped headstock, rather than the narrower Gibson Melody Maker style one - which most early Olympics had. Not exactly rare, but certainly less often seen than the early, or later batwing styles
So, it's value as a
vintage guitar is not a great deal higher than the value of the parted-out body. It is a nice piece of wood, but unfortunately complete ones sell for $600-$700. With the missing parts costing $200-$300 on ebay, it is a false economy to attempt to restore this, unless the price is very low. It might be better suited as a player with a pair of better pickups, to be honest...
So, if there has been no refin, and no extra routing you are looking at $300-$500 - but refinished $200-$400 - obviously headstock repairs, a broken truss rod etc all reduce this value.
Good luck with the sale!
