Prop/Propeller from an 18' Classic OMC

I have what I believe to be the original Prop from my 18' Donzi, which I sold a few years back. It has only been in fresh water and is in perfect working order. I had bought an extra to have on hand. The Model number shown on it is 394755 and it is a 14-1/2 x 24.

Below is the ad showing the Donzi this prop was on. I had to start a new user name as I got locked out of my prior one due to moving and couldn't reset it.

Not really certain what these are worth, but know I paid $550 for the replacement I purchased. I'll start at $400 OBO.
