An Australian man prospecting for gold with a metal detector has unearthed a 145-ounce gold nugget valued at $250,000 AUD ($190,282 in U.S. dollars).

Tokyo is hosting the 2020 Summer Olympic Games, and is considering using their surplus of gold and silver e-waste to create its medals.

The medals were offered at $34.95 per, and the maximum household ordering limit of two of each medal, for a total of four medals.

For 2015, sales through the end of August totaled 421,500 of the American Eagle 1-ounce gold bullion coins. How is the coin doing this year?

According to the investment research firm Zacks.com, palladium is one precious metal that collectors should seriously investigate.

“Significant growth in the precious metal trading activities of the company’s Bullion division made a major contribution to this outcome," the Royal Mint said.

The U.S. Mint was nearly sold out Aug. 9 of its maximum production of 1-ounce platinum 2016 American Eagle bullion coins.

A sales-record three-peat for American Eagle silver bullion coins is starting to look less likely after the U.S. Mint reported its slowest sales month in years.

Authorized purchasers may now order as many American Eagle silver dollar bullion coins as they want after the U.S. Mint lifted its weekly allocations July 18.

Silver and gold were among the top 10 investments during the first six months of 2016, according to the Wall Street Journal.

Even as some authorized purchasers trim their silver American Eagle bullion orders, they have lots of unsold inventory. What does it all mean?

The June 2016 American Eagle silver bullion sales total was down significantly from June 2015, the first monthly total that was lower this year than last year.

2016 sales by the U.S. Mint of silver American Eagle bullion during the first six months of the year are 20 percent higher than the same period in 2015.

Driven by increased buying from Asian investors, silver broke through the $21 per troy ounce barrier July 4 before closing on the London exchange at $20.36.
