Can You Explain Crown Coins And Minor Coins

A Crown was originally a British coin which was equal to 5 shillings. It was originally a pretty big coin (28+ g, .900 silver, ASW .8409 oz). When the British moved to .500 Silver, then copper-nickel, the Crown remained a huge coin. Nowadays, the word Crown-sized coin refers to big coins, whether they have any silver in them or not. I'm not sure if there is an official size that a coin needs to exceed in order to be considered "crown-sized". As for minor, think the opposite, often the word minor is associated with small silver pieces. Again, I don't know the exact size that makes a coin a minor.

"Crown" and "minor" are generally fuzzy terms that are used by world coin dealers to categorize their coins by size.

A "crown", in this general sense, is basically any silver or silver-looking (eg cupronickel) coin that can just fit into the largest size 2x2 holder. British crowns are the standard size, although US dollars, Spanish dollars, German thalers, French ecus and 5 franc coins, would all qualify as "crowns".

If a coin is too big to fit into a 2x2, it's called a "maxi-crown".

A "minor" is technically any coin not made of gold that's smaller than a crown, though often the term is limited only to the smallest coin denominations issued by a country, or coins that are physically "small".

In the US series, silver dollars and Ikes would be considered "crowns". The ½¢, 1¢, 2¢, 3¢, 5¢ and 10¢ would definitely qualify as "minors", though the 20¢, quarter, half and modern (small) dollar would technically qualify, too.
