Hartzell prop year and value

[Rocky]

For years I admired my dad's Hartzell prop, but now it's time to sell it so he can head to FL while I'm stuck in cold MN. Does anyone have any idea how old it is or the value?
98" length, 8 holes, 4" center hole
Design 667|62
AC 10 12|99954
Engine R |680|9
Airplane IE 0|49
After reviewing your website I think it's a "Modern" prop from Boeing PT-13, engine Lycoming R-680.

Hartzell did not publish a list of serial numbers/dates of manufacture. Most of those are 50 or 60 years old.

Value depends on its condition.

I was told that an antique clock was in center, but it's gone now

Does anyone know the value to sell this prop?
Thanks
