Ball Jelly jar?

[Hoosier49er]

I posted this one in the jars forum and didn't get any takers, so I'll try here too.
This one stands 3 3/4" tall, and is 3" wide at the top. It has ten flat panels around the bottom, with "84 MADE IN THE USA 27" embossed around the lower edge. There is a double-dimpled ring on the bottom with nothing else there. There are no threads at the top, but I have seen jelly glasses like that. It has the registered Ball logo, so I know it is fairly recent manufacture, but I've never seen on of them before. I couldn't find this one in the Red Book.
Can anyone tell me what it is and what it might be worth?
Tahnks in advance!

I know Ball made a lot of different types of jars, maybe more recently. I also believe they were eventually bought.

I have one I have never posted that looks like maybe a mustard jar. Couldnt find out anything about it on the Ball site.
