This is someone who quite clearly has a delusional sense of value to say the least, maybe he's related to the weirdo in Whitby, Ontario? Clarion was a brand name for radios manufactured by the America Transformer Company or Amertran. I haven't heard or read anything bad about them but there isn't really anything unique or special about Clarion sets, they are just your typical 1929 to 32 TRF set with your typical string of 2.5 volt AC tubes, like a hundred other sets of the same era. On top of that they are a bit of an off brand so nobody is really seeking them out like a Zenith, or an Atwater Kent, or a Philco of course.
Typical TRF late 20s early 30s consoles don't usually crack the $125 mark in good original condition, and a lot less then that if they need cabinet work or have parts missing. The reason being is that they are all pretty similar, similar circuitry, similar cabinet styles, without reading the name on the escutcheon it's hard to tell them apart sometimes. I have a few myself and I doubt whether I paid more then $75 for any of them.
