Most people are scared to let their toddlers handle money.
I'm happy daughter is the type who knows she shouldn't put anything shiny in her mouth. At an early age, I told her "most of the time when it's shiny, it's usually not fit to put in your mouth." That includes uncooked fish, shiny shoes, glitter polish, colorful balls, decorative stones & small coins. My mom-in-law used to babysit her all the time & she allowed her to play with coins at four months (under close supervision and a ton of wipes & hand sanitizer!)
