Each to his own level of comfort, Annie, right? I'm a firm believer in challenging my immune system to keep it strong and healthy - I let my toddler son eat dirt so he'd see it didn't taste good, AND help his body deal with germs. Worked out fine! Now, as for pennies, I'd certainly line the crust with parchment or foil, and wash the pennies; but beyond that, I wouldn't worry about them looking "dirty." Thanks for connecting here - PJH
