My sister just got back from a day trip to Mexico and brought me back some coins. One is a $5 coin with two different dates,2010 on the outer ring that looks doubled on the zeros (why did they do that)and the center is dated 2009. Is this normal?

. Here is a list of the others, do any of them have any collector value: $5=2006,$2=2005 & 2010,$1=1997 & 2001 & 2007 & 2010. Thank you for the help.
