First post looking for some information and/or advice.
I have an old full bottle of Tequila Almendrado. I was told it was obtained by my great uncle on a trip to Mexico around about World War Two or shortly after but the dates might be wrong.
The bottle is made of very old appearing green glass with air bubbles and imperfections throughout. The label says Cuartro Coronas which appears to be the brand. Under this it says Calidad Extra. The small back label says that it was made in Monterrey.
There is a numbered Texas liquor stamp on the bottle for 1/5 gallon at 28.16 cents. The bottle appears to have a metal screw top though it is under a green, white, and red seal. It has a "Federal", presumably Mexican, paper tax seal over the cap which says $0.15. Some of the liquor appears to have evaporated in that the liquid level is lower than I would expect. The bottle does not seem to leak when tipped on its side for a prolonged period. There is quite a bit of sediment in the bottom.
I would like to sell the bottle to a collector but I have no idea how to go about it or what the value is. I could just put it on eBay but there doesn't seem to be much traffic for things similar to this. The amount of Texas tax and the screw top make me think this isn't that old but it seems to be fairly rare or at least unusual in that I can't find much about it online.
I have attached a picture of the bottle. Any help is appreciated.
