These are awesome. I’m actually not using pennies for them, but 3/4 inch plastic bingo tokens and they’re perfect. Since the bingo tokens are all different colors, it adds some variety to the look. Obviously, they’re not as heavy as a penny so I question the long-term durability, but also don’t have the downside of new pennies developing verdigris if indeed new pennies are used. Downsides to either way I suppose and comes down to a matter of personal preference. Thank you, Burger Tokens, for such an excellent product!
