Hyvis Motor Oil Mileage Meter Coin

[doctorbb]

Anybody ever heard of these? I researched on the internet and seems quite common from the 40's or 50's. I've never seen one before. I found it at an old school. It was on edge and got a signal that bounced from silver to nickle and everything in between. So I was curious and dug it. My heart kind of jumped when I first saw it, thought it was some old large coin. Sorry there's nothing for scale in photos but I downloaded these off the internet, the coin I found is very discolored and did not photgraph well. It's a little larger than a silver dollar.

Correct again, Aunt Gyps; http://forum.treasurenet.com/index.php/topic,17392.0.html
Although, perhaps from the 30's, just based on the the old thread.

According to www.dantiques.com, this was an early version of today's "high mileage" motor oils. According to the age of the engine, you were supposed to switch to thicker grades, of which there were four.

Yep. I found one about a year and a half ago and it is one of my favorite finds. It cleaned up real nice. I found it at the base of a tree on a vacant corner lot. I was told that years ago there was a gas station there. It was one of the first finds with my GTI 2500 I think, and it showed up on the silver dollar icon and sounded like silver. Great find, not worth a whole lot but there are several collectors of petroleum industry tokens. Monty

The coin (medal) I found advertises piston rings, but its from the same time period, similar in form and design, these must have been a popular way of adbvertising or sales gimick, no commercial value, just a medallion.........

do a search under "pretoliana"
There is a collector group with a publication called "Check the oil"

Found one today in Webster, MA. It was all corroded similar to a large cent and all I could make out at first was 00. Was thinking it read 1/100....heart sunk when I saw it was a token. Still a cool find though.
