Copper plated pottery footed bowl with handles

I have this copper on pottery footed bowl.  I bought it in a junk store in Arkansas in the 1960's just because I thought it was very pretty.  I have enjoyed it all these years but I don't have a clue how it was made. It almost looks ancient.   i think it probably is handmade.  It is 8 3/4" wide, 13 3/4" long and 4 3/4" tall.  It has water sediment on the inside, probably had been used for a plant.  The copper is mostly gone from the inside of the bottom but the copper is still completely over the outside.  There are no identifying sympols that I can tell but there are marks like a fork type instrument was used to press the copper on the bottom.  There is a small wire loop on the bottom and there are 2 rusty lines in the pottery on the inside.    I would love to know who, where and how it was made and if it has value what the value is.  I am attaching pictures which were taken some years ago after I had cleaned the copper but since I haven't cleaned it again the old patina is returning.
Thank you for any help you can give me.  Margaret Witt in Oklahoma
