If it is a collection of 50 cent coins, it could be worth a lot, or not that much. It depends on the dates of the coins and the condition. 50 cent coins from before 1965 are worth more because they are 90% silver.

The collection and/or study of coins is called Numismatics.

Numismatics is the study of and collection of . . . . money: coins, bills, and so forth.

This question is not very specific and, therefore, the answer is going to be a bit creative (hope you don't mind!). Make a normal square with 9 coins (3 x 3) and then stack the left over coins however you like on the 9 coins! :-)

The noun numismatics is the study or collection of coins, paper currency, and medals.

If there are 14 rows in the triangle, then there are 14*(14-1)/2 coins in the arrangement, i.e. 91 dimes. To find the value of the collection, simply multiply by the value of a dime. I believe this is 10 cents, so the coins are worth 910 cents, or $9.10.

Collection of coins is called collection of cons only n there is no specific word for it. It is different from numismatics as numismatics is the systematic study of coins. Mere collection of coins cannot be called as numismatics.
