It is a 5 cent gaming token for the Hiawatha Horse Park in Ontario, Canada. There is a 25 cent token like yours on ebay right now for 3.99. Nothing in the sold category. I would imagine yours would be worth anywhere from 25 cents to a dollar or two to the right person.
Seems to be a 5 cents slot machine token at Hiawatha Horse Park in Ontario Canada. The slot machines were banned in 2012 and recently came back. As for age, it's pretty much impossible to tell the exact age. I'm not sure when the park opened or slot machines first came into operation, as that would give the earliest possible date. http://www.ontla.on.ca/library/repository/ser/189045/2002-2003.pdf https://lambtonshield.com/slots-returning-hiawatha-horse-park/
