I've mostly seen them in PSA5 or lower. I haven't looked at the pop reports but I was happy to find this at a very reasonable price. The card has a deep gauge line in it from the top right corner. If it didn't have that the card would grade a fair bit higher as most the corners are sharp.
I'll have to look at the pop but when I searched on ebay there was nothing higher than a 5 and a PSA3 was twice the price this was.
