A question about PSA putting their cards into sleeves in the holders reminded me of this guy who tested PSA graded cards where the card was not in a sleeve to determine if the card could be damaged by a) attaching it to a paint shaker and b) putting it into a clothes dryer. He determined that the card was not damaged in any way on the Paint shaker, but the clothes dryer wreaked havoc!!
Thought i'd post these for you guys to have a look at -
So in closing, unless you happen to leave your PSA graded card in the pocket of your shirt when it goes into the clothes dryer, then you shouldnt be too concerned about there not being a sleeve inside the case!
