I believe you are asking, how can I sell my Coins for cash (if Bank Notes = Cash).
You have several options. I would recommend calling in a coin dealer to estimate the value of your coins. some may be valuable, some common, and some just worth their “Smelt”[1] value.

Selling to a reputable dealer, collector, (or pawn shop) is the fasted route to liquidating your collection for cash. Keep in mind that these buyers are looking for values below market, to reduce their risk and make a profit on the eventual sale; you may be offered between 10 and 70% of the retail value of your coins.
If you have the time and ambition, you can use the internet for valuing your coins, and sell them on your own. Craigslist, EBay, and some of the popular coin sites (forums and for sale sections) are your best options.
There are even books on this topic:

Many public libraries have books on coins and periodicals on prices, that you can access for free.
I buy and sell coins on EBay and from individuals, at estate and yard sales. It’s a fun hobby for me, especially when both parties feel they got a good price!
You will need to understand coin grading, as there are many valuations for coins based on condition (grade). Circulated coins (pocket change) is not worth as much as graded and certified “Mint-State” coins.
