Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion accuracy of pricing - questions from a newbie

Hello petroliana pros ; forgive the stupidity but why is this sign priced this way ?
Is it super rare or large ? Do signs with this type of price point change hands often ? Hopefully someone can tell me why this is priced this way
thanks in advance
