A dealer has a
'53 tweed Princeton for sale, for only $1500. I bought the same amp (granted, a while back) for $400, because the tweed was in very rough shape, almost ready to fall off. Worth to note at that time, and excellent example would have fetched around $1000.
Either way, it would be classed by a dealer/collector as in much better shape than what Plexi50 started with. His amp had
no tweed,
wrong grill cloth and
non-original cabinet corners and bumpers added. The selling price then becomes speculative at best, because it's not even on the radar of collectible vintage prices. Therefore, as always, it's worth whatever someone will pay for it.
So now Plexi has a Excellent recovered Super. Would call it Near-Mint, but the control panel has honest and significant wear. But the amp is unmolested, and it now looks right and tight from across the room. The amp's value then went up, even though it will fetch somewhat less than an all-original amp in the same physical condition.
Up until I joined the military in 2000, I frequented a number of vintage shops in Nashville, made friends with the dealers, went to vintage shows around the country, and bought/sold guitars & amps either belonging to me or for a couple dealers I occasionally helped out.
