Is there a special term for a blank coin, before the image is struck?

Planchets ready for minting

Definition: planchet is a prepared disc-shaped metal blank onto which the devices of a coin image are struck or pressed. The metal disc is called a blank until the time it passes through the upsetting machine which causes the rim to be raised. Once it has a rim, the disc is called a planchet.

When referring to ancient coins, and coins which were made from cast metal discs rather than machined metal discs, the generally preferred term is flan.

 

There are really no hard and fast rules about the usage of these terms in ancient coin collecting, and you will sometimes hear ancient coin blanks referred to as “planchets”, even though they were made from cast metal.    In modern machine-made coinage, the distinction is very clear: the disk is a stamped metal “blank” before getting the rim, and a “planchet” afterwards. A coin that is ready to be stamped is a “Blank” or a “Slug” – From What is a Planchet? from About.com


When the coin is struck improperly, and gets into circulation – the resulting coin is usually prized by collectors as a Mint Error,  and may be very valuable.
Example of Mint error – US cent struck off-center.

Welcome to Pocket Change Riches

By Alan Chenkin, who jingles his coins…

With Credit cards and smart phone payments we hardly need to carry cash anymore.  While it makes me a bit of a throwback, I will miss the bulge and jingle of change in my pocket.  For example, slot machines Have been using paper money, credit cards, for wagering and paper slips for winnings when you cash out.  They used to have big trays to catch the players winnings, and the noise of all the coins dropping was like a siren call to all the nearby gamblers.  Casinos used to distribute sealed towelettes to slot machine players because of the dirt that would accumulate on their hands from handling coins while playing.  And kept coin cups nearby to hold the winnings of the lucky players!

 

In my man cave, I have always been in the habit of throwing my loose change in a cup on my dresser every evening.  every so often I will sort it out, and hunt for coins of value;  old silver coins – the odd foreign penny or farthing; sometimes a Euro – so I can celebrate my “find” and put them aside.  For the older silver and well preserved coins I have “Coin Flips”, for keeping the coins clean after I wipe them with a cotton sock, er, “coin cleaning rag”.

Where are some places to buy coins for collecting?

by Alan Chenkin, Novice coin collector and hobbyist
Coin dealers, EBay, Craigslist, and from friends and acquaintances are great sources. Let people know you are looking for coins, and you may be surprised.
If it sounds to good to be true, it usually is. consider buying a test kit if you are buying gold and silver; GOLD TEST KIT
When you acquire and store collectible coins, just wipe any dirt off them with  special coin cleaning cloth (an old sock), and put them in a “flip”, coin book or folder.  If you want to get a child or teenager into collecting, you can get them a whole kit from Amazon or eBay.
Coin collections start to grow quickly, so you need to keep them in an orderly fashion.
Best of luck!
Oh, and you might need one of these:
Keep in mind that coins can get heavy, make sure the safe is on a floor that can support the weight !
