Many modern gold coins including the American Eagle and the Kruggerand are not pure gold.

I have the 2013 reverse proof buffalo PCGS PR70 Chicago ANA release and that coin is so much hotter it's not even close.

I don't own any Titan Gold coins or any other buffaloes beside my reverse proof. I think the Titan Gold are great looking as well but the buffalo is an iconic design which has been around for 101 years.

That's what I said earlier.  Great minds think alike.

The buffalo is a great looking coin design.  No argument here.  I was just talking about the finish. 

If you hold a proof grade buffalo next to one of the Titan coins, you'll see that the texture on these provides a higher contrast that makes the Titan appear "brighter".  From what I've been told, this texturing isn't something that can be done on high-production coins like the buffalo because the dies wear down too quickly.

Hence the key word "typically". If you compare all modern world coins from all country's mint, they're 999 gold. Americans are always the odd ball when it comes to standardizing, such as inches/foot and pounds/ounces.

The premium is calculated at about the break even point for this batch of 100, and includes the average cost of shipping and insurance, as well as a small percentage margin for coin dealers that are reselling these. 

We sold an initial run of 25 coins at a premium of $450 and ended up losing money, but we were also able to lower production costs by making 100 coins at a time for this batch.

Hopefully we'll be able to make more than 100 in 2014 and turn a profit on this product, but I'm mainly just happy to be able to bring them to market.

As an aside, we're actively looking for U.S. mints that do high quality gold coin production and if we can lower costs, we will absolutely lower the premium.

PCGS or NGC won't grade these coins because they're not legal tender anywhere. However, you can get ANACS to grade them, as they're considered as "medallions".

Beautiful coins! Sent you a PM.
