Is it common among US modern stamps?

These two stamps shown come from one lot of covers. The red ink of the right stamp is out of allignment. Can you see it? 
I think such gap is rare among Japanese modern stamps, however I feel common among US stamps. How do you think ?

What I got at the Bazaar in Osaka (Japan Stamp Auction)

I've been to Osaka for one night to participate in the Jpana Stamp Auction. Because I usually use overseas auction houses, I bid mainly on telephone but little going to the auction room. But recently I change my mind to participate in the auction room as much as possible. The reason is I realised the auction room is, especially that of the Japan Stamp Auction, hub for the philatelists in this area, I mean west side of Japan. It is a wonderful chance for me to meet many philatelists of various specialities. It cost me around 600USD to visit Osaka from Tokyo including one night stay, however I like the chance to meet many philatelists as I'm new to philately.

I can meet many philatelists there this time and they advise me and I feel interesting talking with them. Thank you very much. By the way besides bidding in the auction, there are some dealers and philatelists selling stamps like Timbre de Marche in Paris. I got many international covers before the WW2, however what I'd like to show today is panda stamp. This stamp was issued in 1982 and the first Japanese stamp depicting Panda. As I like this stamp, whenever I find it, I bought all of them! Some day I'd like to exhibit thematic collection of Panda!
