I own mostly Philippines coins issued by the central bank. I also have canadian coins, a US penny, and some old bagon lipunan Marcos coins, lots of them actually, that I’m planning to sell in the near future. Sometimes coins are a nuisance because you need to count them, unlike bills that its easy to dispose and you just wait for the change. But loose change are good for savings. This can really add up to a fortune if you only put them in a place. Big things have small beginnings anyway.
