Prices May Rise for US Mint Numismatic Platinum and Gold Coins

American Gold and Platinum Eagle Coins
Two of more than a dozen U.S. coins that should see price increases on Wednesday.

It looks as though prices will rise for U.S. Mint numismatic gold coins, commemorative gold coins, and platinum coins, if prices of the precious metals they contain do not drop significantly on Wednesday. Recent trends of gold and platinum prices in the London market show a consistent up tick of prices since last Thursday.

In a nutshell, seventeen gold coin prices will change unless the Wednesday’s London PM fix for gold plummets below $1,600.00 an ounce.

[Update: The U.S. Mint updated the numismatic coin prices before noon ET. New prices are provided below.]

Affected coins include six of its First Spouse Gold Coins, six of its numismatic American Gold Eagle products, two of its proof American Gold Buffalo coins, and three of its Star-Spangled Banner commemorative gold products. For the proof American Platinum Eagle coin, its price will change unless platinum’s PM fix falls below $1,450.00 an ounce.

The United States Mint evaluates a weekly average price of the two precious metals on the London Fix to decide whether its coin prices need adjusting. The formula includes figures from Thursday’s AM fix to Wednesday’s AM fix. Then, the Wednesday PM fix is the last indicator.

The current range that was in place allowed the weekly average London Fixes for gold to fluctuate between $1,550.00 to $1,599.99 an ounce and platinum to vary between $1,350.00 to $1,449.99 an ounce. Yet the averages as of Tuesday PM came to $1,621.87 an ounce for gold and $1,487.12 for platinum, making the Wednesday AM Fixes for each nearly inconsequential.

The latest U.S. spot prices have gold near $1,623 an ounce and platinum around $1,484 an ounce. Essentially, coin prices are going to rise by one tier on the U.S. Mint price grid unless precious metals tumble by the Wednesday PM fixing.

The table below describes the expected rise of coin prices.
