Answer:
A gold coin is a coin that is made mostly or entirely of gold. Most gold coins minted since 1800 are 90–92% gold (22 karat), while most of today's gold bullion coins are pure gold, such as the Britannia, Canadian Maple Leaf, and American Buffalo. Alloyed gold coins, like the American Gold Eagle and South African Krugerrand, are typically 91.7% gold by weight, with the remainder being silver and copper

Answer: six 50¢ pieces.
Step-by-step explanation:
6 × 50¢ = 300¢ OR $3.00
13 - 6 = 7
7 × $1 = $7.00
Therefore,
$3.00 + $7.00 = $10.00 (in thirteen coins).
