An 1939 F-5 Gibson Mando is potentially a “name-your-price” item.
Here’s $95K for a 1926 one

A 1939 could not be a true Lloyd Loar (due to late date) but here’s a LL for.....ahem.....$675K! (ridiculous)
Seriously, a 1939 F-5 could potentially go in the $60-$75K range. That is a major, major instrument.
Yeah, I know. I’s jist testin you. : ) We bought it for $1000 in 1968. It’s not for sale.
Oh BTW, that one for sale on e-bay looks pretty much like ours. It’s a Fern, and not a Loyd Loar (pity).
