I've pondered this since gold surpassed platinum back in 2011. I'm thinking to mysef... "Does the U.S. Mint know something I don't"? I'm sure the numbers are there only for traditional purposes but STILL. Seems to me that the U.S. Mint might make a change to their coinage? How about putting $75 on the Platinum Coin and $100 on the Gold Coin? That's what I love about the U.S. Nothing really makes sense. I mean, for instance. You can purchase 1 silver oz at spot price of $17.23 or 1 share of stock in Amazon for $978. I love America. In order to profit living in the U.S. you must follow the money and invest accordingly.
So back to the title at hand. Do you think Platinum will ever catch up to Gold again? I'm sure it will surpass gold at some point in the far off future. In my eyes any investment in precious metals is a good one. Gold, Silver, Platinum, Palladium (being the 4 big ones). There are also many other metals you can invest in that will eventually rise up and shine. The thing I like about precious metals/semi precious metals is that they are real. You can hold them, show them to your kids what real money looks like, or in the case of SILVER you can use a bar as a door stop or a weapon.
Of course you might think about cryto as well. Seems to be a future in it.
Just some thoughts. Have a great day. PS: Here is a list of precious/semi metals you can add to your portfolio: Web Site: http://www.infomine.com/investment/metal-prices/
