I actually am digging the coins irregardless of their material, however when push comes to shove this stuff is a cost... The folks at Hasbro claim cheap costs, but it's a cost and I think they bite it more thanthey let on sometimes on stuff like this.
I'm a fan of just getting a great figure, none of these gimmicks. The coins are better than holographic figures and I love the holder for them, but I could do without it all and just get figures that I personally felt were WORTH $7 a piece...
In 2006, Hasbro's not delivered that level of $7 figure quality steadily. It's been hit and miss at best when you get figures like Jerjerrod, Derlin, etc... $7 is tough to choke down for those unposeable, under accessorized figures. I'm warming up to the coins though, at least a little bit.
