Bullion Question

The reason it is so hard to find Rhodium for sale is because its demand is well exceeding the supply. Just because it has a price tag of $9,500 doesn't mean it will be easy to get at that price.

Think of how easy it is to buy 10 ounces of gold on ebay a coinshop kitco or wherever. When looking for an ounce of pure rhodium for about the same price as 10 ounces of gold you will have a very tough time finding it especially for near spot price.
There is plenty of gold to go around but when it comes to Rhodium the same cannot be said. -PP

As has already been answered, no. Rhodium was only discovered in recent times, and no known ancient coins were "accidentally" made with anything more than minute trace amounts of rhodium.

I don't think anybody's made rhodium coins yet.


Yep. This was the site in question. They sell just about any element you care to name, and many of them in "coin" form. With it's high price, rhodium isn't one of the ones they currently coin, or have plans to do so, but if you feel the need to hold a piece of the most valuable bullion metal in the world, they will sell you 1 gram pellets (6mm diameter, ball bearing sized) of 99.9% pure rhodium at market rates.

Personally, I think investors should steer clear from such "utilitarian" precious metals. Investors merely drive the price up, and their holdings deprive the world of pieces of metal that could otherwise be put to productive use. Secondly, the market is highly speculative. Scientists may develop new, cheaper substitutes for rhodium in the various applications where it's necessary, and geologists may find rich new sources of the metal - both of which could cause the price to collapse.
