user35621: Is there any way I can find out how many Bitcoins existed at a certain point in time?  Are there charts where I could, for example, see how many Bitcoins were in existence in 2011, so I could compare to the quantity existing today or something as such?

user23123: Yes. This chart from blockchain.info is one. There are probably many more.
