Richmond Va megadealer Paul Sims son started / runs Yesterdays Change. Paul Sims had a so-so rep, some complaints about overgrading, selling dipped and or whizzed coins, etc. Don't know why son broke with Dad to start own company. Paul Sims has since died, don't know if Paul Sims Coins is still in business, but don't see their huge ads anymore.
