Hello, I am about to buy a Paul Reed Smith Custom 24 Gold Top made in 2011. I attach here the certificate of authenticity. Everything seems to be ok with the guitar as far as I can see in the photos. The issue is that is does not have a readable serial number. According to the owner, everything is stock and also sent me an email in which he bought the guitar to Axe Palace. Could this affect the resale price? The owner says it is due to the wood being dark. However, I couldn't find information about faded serial numbers in PRS guitars. I live in a place with a lot of humidity, but I don't know if it could be a factor to considerate because the guitar is just from 2011. I found this exact guitar in Darrel Braun's Youtube channel and it has a fully readable serial number: Minute 2:10 Thanks in advance!
