Just wanting to get a Idea of what I should spend on this.  I have the opportunity to buy this rare sign from a guy that used to run wrecker and got this from state workers as they where changing signs to the 75MPH Speed limit.  I called a sign collector I know that travels the Northwest looking for signs, he's never seen one.  This sort of confirms the rarity of this sign for me.  Before I shell out any cash for this I called a freind of mine at the State DOT he also says he doesn't know of any of these signs that didn't get repurposed. there were two sizes a state highway sign that was smaller and a Interstate sign that was larger.  Any help with this would be great.  I know the age value of this is nothing, but it seems rarity is king with everything.   Any of your thoughts would help. Thanks Pete
