Howdy howdy, first time posting since the move to the new site. I have some signed gold stars where the PSA case is signed, and I moving them from display to storage. I was wondering the clear sleeves (to go over the PSA case to prevent dust) will damage the signature.
I would not use anything that directly touches the signature since the friction will likely erode it over time. I have some strange PSA rigid plastic cases that ultra pro made (and I’m 99% sure they don’t make them anymore) that I have placed over my one signed slab.
I think a perfect alternative is the holder that @cinnaminhbun made https://gradedguard.us/ as it has a clear plastic screen on one side that could protect the signature
