For a long term investment? Canadian Gold Maple Leaf or, American Gold Eagle, or South African Kugerrand, or Australian Gold Nugget, or Chinese Panda?
That would be one of the factors I would suggest as well. Another might be to look at historical premiums and see if any of the current options is undervalued (for example, let's say the panda is $10 more than the rest but prior years sell for $20-$50 more, then that might be the better option).
I would choose the Canadian Maple Leaf out of those options. However, if a US Gold Buffalo was a choice, that's the one I would choose.
Maple Leaf or Krugerands...closest to spot for "stacking". The American Eagle metal composition is the same as the Krugerand...it was designed to be a direct alternative to Krugs after all. I've never been keen on the base American Eagle mark-up/premium prices especially since it's so difficult for folks to get into the "physical gold pool" in the first place. THAT said I AM cherry-picking and purchasing AGE Series key dates and special releases with LOW mintages to compound potential spot + numismatic future values. I have complete researched date sets of China Panda BUT ONLY in the 1/2 ounce denomination that had the smallest pre 2006 mintages (keys) of the entire Panda series. Other denominations in pre-2006 also exhibit low to middling mintages are in the collector realm, and also require purchasing from reputable or specialist sources in mint packaging or slabbed to avoid counterfeits. Otherwise due to their high price over spot and post 2006 high mintages as mass bullion I don't recommend China Pandas for "stacking". One or two contemporary dates are cool for those wanting a global diverse "basket" of gold coin bullion for Type collections.
American gold Buffalo's are the .9999 equivalent of the Canadian gold Maple Leaf. BUT at a higher "nationalistic" premium price. At this point again it's to personal preferences and ability to get your foot into the physical "gold pool". I'd still choose the Canadian Maple Leaf at the lower, per unit, cost of gold.
I like AGEs because even dealers will pay a premium for them. Vermillion Enterprises in Spring Hills, Florida pays spot + $55 for AGEs but only slightly under spot for Maple Leafs.
I like maples for the purity and lower premium, but I already have a Buffalo and Eagle so Maples are next on my list. However its all about whats available and the price. Also I am in north America so this makes sense. Not sure this would be the case if I was in the EU or elsewhere.
Theres a difference in cost at the time of purchase, Maples tend to be allot less then AGE,S so it only makes since you would get less when you sale them.
I've been considering picking up a Gold Maple Leaf Bullion locally. I don't know anything about investment metals though. The guy has a coin in a bag. Don't these things need certificates? Is his 10% premium a bit steep? He also has a 3.5% payment fee. Is this normal?
What do you got against Krugers ? In gold coins there is nothing more recognizable in the world, they are it !!
