I agree with the previous price quote.Some of these can easily bring 10-20-30+K or more.

Lighted & neon signs are highly desirable by many many people right now,more then ever.
Find out if was really a porcelain Neon lighted sign to begin with,(not just a flat porcelain sign that was later drilled & canned for Neon),as well as not being a 3rd world repro.
Just like the car hobby,many signs that were/are being sold @ auctions today were never neon lighted in their infancy,or were even made overseas & then weathered to look aged.
Some will buy single or doublesided non neon signs,take them home,drill into them & neon light them.They now have a neon lighted sign to sell as "original".
Just like the car hobby,there is a small private database of people keeping track of others buying signs both in person,or on the internet to see how they are resold..i.e. a repro or non drilled neon porcelain sign that XXXX just bought,turns up as a freshly drilled neon lighted sign 2 months later.

The market is being overwhelmed with doctored signs like I just described,as buyers don't do their homework.Rust,chips,dents,scratches & stains can easily be replicated to perceive age & wear,not that I am suggesting yours is.
Although it looks very nice,I can't tell from your photos what you have there.
