Collecting Mint State or Proof Gold Eagles and Buffalos can be very lucrative for investors. The American one Ounce Gold Eagle was first minted in 1986. The coin is 91.67% pure .9999 gold. It is also made with 3% silver by weight and 5.33% copper.
The added metals make the Gold Eagle sufficiently hardened for circulation. Circulation never was the intention.
The US Mint Gold Buffalo one ounce gold coin is pure .9999 gold. This makes it softer and easier to scratch. It was never intended for the coin to be circulated.

PCGS, also known as Professional Coin Grading Service defines a First Strike Coin. “The PCGS First Strike program designates coins issued in the first 30 days of the Mint’s release.”
The US MInt does not certify the coins as “First Strike”. Certification is done by PCGS or NGC. This has turned the First Strike designation into a quagmire for collectors. However, the Mint State 70 designation still gives the coin Superior value.
On most current dates, I could not see much value difference between an MS70 and an MS70 First Strike. I personally believe a slabbed and graded coin that is MS70 would be a better long-term investment.
First Strike Coins were first promoted by the grading services back in 2005.
