Because the human finger has ridges. (The thumbprints tell it)!
Zero.Dimes have ridges. Quarters have ridges. Pennies and Nickels don't.
No, a magnet cannot pick up a nickel because nickels are made of a non-magnetic material (75% copper and 25% nickel). Magnets are attracted to ferromagnetic materials like iron, nickel, and cobalt.
Glaciers pick up rocks and soil as they move across land. When the glaciers melt, they deposit the rocks and soil. Today there are ridges of rocks and soil where glaciers once were.
"Golden" dollars, pennies, and nickels. It's not that hard, just grab a fistful of change and check it out.

folding uplift and erosion
You could have: 8 nickels and 1 penny or 6 nickels and 11 pennies or 4 nickels and 21 pennies or 2 nickels and 31 pennies. The option of 0 nickels and 41 pennies is excluded by the necessity that the amount is made up of dimes, nickels and pennies; 0 nickels would mean the $1.21 was made up of dimes and pennies only.
Those ridges date back to when some U.S. coins were made of silver or gold. Without reeding (the ridges), it would be easy for someone to scrape off shavings of the metal to keep, and then the coin wouldn't contain its full value of metal content. Cents and nickels were of such low value and lacking precious metals that reeding was unnecessary.
The minimum number of quarters, pennies, and nickels needed to make up 123 cents is 4 quarters, 4 nickels, and 3 pennies.
Either 30 nickels or 6 quarters or a lot of combinations of the two.
Friction ridges or fingerprints are formed by the patterns of raised skin ridges in the papillary layer of the dermis. These ridges are made up of dermal papillae, which project into the epidermis and create unique patterns that form fingerprints.
