That's a lowball PC for the perfect eternal. 100k30-40+, imo. People will be willing to pay more for tyrian perfects than their inscription counterparts.
normally i would agree wilderness but people don't pay for anything anymore. tyrian and inscriptables are becoming the same price except for a few ectos
yeah unfortunately the mindset has become "why pay more for non-inscrib if i can get it way cheaper for inscribable" and consequently "why pay so much for an inscrib when i can get a non-inscrib for a little bit more" vicious cycle of reasoning but it's happening. ah well.
