Because RuneScape is written in Java, the game itself has Java options and restrictions. This means that the maximum number of characters of each item is 2^31-1 = 2,147,483,647. Of course you're allowed to have several slots of cash, but only one in your bank. The others must be kept in either Grand Exchange (which holds up to 6 slots in members and 2 in F2P) and your inventory, which can keep one slot of cash.
I would say probably about 200-202 but in karajama is a bank i think so you could spend over 1mil coins or something.
The number of coins that can fit into an empty piggy bank depends on the size and capacity of the piggy bank, as well as the size and denomination of the coins. Generally, you could estimate by counting the volume of the coins and comparing it to the volume of the piggy bank.
Members get 496 bank slots, while free players only get 68.

There are many cooking ranges on runescape. The best cooking range on runescape is at Al-Kharid. It is the closest to a bank.
The origins of the term "piggy bank" come from the Old English word "pygg" which referred to an orange clay. This clay was used to make many things including dishes and jars to hold spare coins. The word pygg sounds much like the word pig, and probably was changed due to misunderstanding. I guess from there, the pygg jar for holding coins became a pig shaped jar, or piggy bank, for holding coins.

There are many coin collection machines available through the country. So you can use these machines to deposit your coins and get them converted to cash. The machine will directly credit the money you are depositing as coins into your bank account. You can then withdraw it at a later point of time when you want.
