3' Coke Button Sign

[66GTO]

I was hoping someone could educate me on the 36 inch coke button signs.  I'm a newbie when it comes to signs.  The disease of soda machine collecting is starting to branch out into soda signage now  

The one I'm considering is red with the bottle pic and "Coca-Cola" script.  No markings on rim, such as date, model #, etc.

My questions are:

Was this made in both porcelain and painted versions?  If so, which one would have more value/rarity?

Was the 36 inch ever reproduced?

What is a range of value for one in good to excellent condition?  (I have no pics to help, sorry)

There are repro's of the 12 or 16 inch signs. According to Petretti's price guide, there is a tin and porcelain in 24 inch size. The 36 inch ones command lower values. There were many different versions made, some with decals applied. I have a tin sign that looks to be 4 feet wide in rough shape.

My 36" button with the bottle has "AM 104" under the bottle. There are no markings at all? I have both porcelain and painted 36" buttons.

I will ask the seller.  They were looking along the rim, not near the image, so maybe there is something....

Not all original buttons have markings
