That's a lot more than 50c. You can get a Nano 3 from China for not much more than that socket. Can't see the length of the pins in that picture either. I'm not sure what type of socket jrlp is talking about, but in my experience trying to use sockets in breadboards is likely to cause poor connection issues and potentially a lot of head scratching. I can usually get Nano/Micro out of the breadboard without any problems, but once or twice I have bent pins, ive just straightened them with pliers.
