The flip coins are always somehow damaged

Alright, those little plastic coins aren’t the most exciting thing in the world, but I enjoy them well enough… except for how horrible they are! Sometimes I have to physically file off a nub of plastic so I can put it in a coin capsule, and I think I’ve got two flip coins that AREN’T damaged somehow. Just today, I got an Evolving Skies ETB and the coin had little marks from what I presume are air bubbles running up Espeon’s back, and a scratch across Glaceon’s forehead! Why is there absolutely no quality control when it comes to these?
