Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums Petroliana Value Questions Value and Rarity of Sinclair Opaline Sign

I recently ran across this Opaline Sign that appears to have just gotten out of the hospital. My questions for our members:
1. How rare is this sign?
2. What would be the date on it?
3. I know that the answer is “Whatever someone will give for it.” However, being in the condition that it is in what do you think the value of this sign is?
Thanks in advance to those who respond,
Steve
