Hello all. I purchased a few boxes of the mystery pins at the sept 11th party. On the box it states that there is ten pins in the set and also 10 mystery chaser pins ( edition size of chaser pins is 150). So my question is, are there only 150 in total limited edition pins? I'm new to the world of pin trading and was not sure. I got a few in the boxes that I purchased. Thanks in advance.
