2012 50 Cent Error Rate?

Hey guys,

So I ordered 2 rolls from the mint last month and got them a while back but didnt want to open them. Trying to get 2 of everything new for both my kids when they get old enough. Anyways I still wanted some singles for a couple of 50 cent collections I'm doing and needed the 2012 but didnt want to buy them for 2.50 or more. O.o. So I went to the Vancouver mint store and looked around then asked the lady if they happen to have any left.. And she said wow you are lucky we have ONE roll. She said they were saving it for her when she got back (from what I dont know.) but by that time she already got some and didnt need it. Woot got my third roll today and opened it.. Not great condition if you ask me I dont think I pulled a MS65 out of the bunch but ah well I filled my MS holes for 2012. BUt what I did find were 3 Error coins. 3 from the one roll. 1 was struck through on one side and the other was struck through on both sides. Now these only cover maybe Less then 5-10% of the coin. The Third coin has a ring around the outside edge of the dots, AND NO it was not on the end of the roll so it wasnt the roll machine mark I see on alot of coins. This one was wierd, it goes maybe 75% away around the coin then stops abruptly and you can see the copper in it. PICS soon to come to lazy right now. I did have two other struck through coins but they were very small and not worth keeping imo.

But seeing this has anyone else seen alot of 2012 50 cent errors? if I pulled three(well 5 if you count the small ones.) from one roll what are all of you seeing?
