A web page that will display the optimal coin combination (fewest number of coins) that fulfills a given dollar value. The web page should take a dollar value as input and interact with an API that computes and returns the optimal coin combination.

$1.56 => { "silver-dollar": 1, "half-dollar": 1, "quarter": 0, "dime": 0, "nickel": 1, "penny": 1 }
$12.85 => { "silver-dollar": 12, "half-dollar": 1, "quarter": 1, "dime": 1, "nickel": 0, "penny": 0 }
