A mixed coin collection is quantified by combining the values of pennies, nickels, dimes, and quarters, rather than counting the number of coins; the total is expressed in cents, typically for collections totaling no more than 100 cents. Reasoning includes skip-counting equal denominations and adding groups, recognizing that different combinations can have the same value and that the order of coins does not affect the total.
To find the value of a mixed coin collection:
Example: You have 2 pennies, 1 nickel, 2 dimes, and 1 quarter.
Now add the groups:
The coins are worth 52 cents altogether. The order of the coins does not change the total.
