I used to own Kruggerands, and I sold them, in order to shift my PP into tax-sheltered accounts. I'm currently 100% tax-sheltered so no coins for me for a couple years until I make more money that exceeds annual tax-shelter contribution rates.
When I get back into gold coins, I wonder if I should keep them consistent, i.e. only buying Eagles, or if it's a good idea to mix and match for whatever reason. I like the idea of consistency, because doing verification tests on the gold will be easier. If they all make the same unique spectrum when bounced on the table, they are easier to compare than if I have multiple types.
I'm shying away from Eagles and leaning towards Maple Leafs or Kruggerands. The gold portion is supposed to hedge against the US, since 75% of the PP is US-based assets. I realize the Eagles are really gold, but since they say US on there, it may cause problems in the event of a US collapse. I'm not too worried about it, and believe the risk is small, but all else equal, I think non-Eagles make more sense for a US-based PPer.
I like the Leafs because they are Canadian, so in the event of US Collapse, Canada may still be recognized. I like Kruggerands because they remind me of international super villians from the movie Lethal Weapon 2. No joke. Ever since I saw that movie, I wanted to own Kruggerands, and eventually, I did. There was also confirmation bias, because once I researched buying coins around 2006, I discovered the Kruggerand traded at the lowest premium of the other coins; then I REALLY had to buy them

The movie-thing is a stupid reason, which is why I am considering standardizing on the Maple Leaf once I get back into it. I'm investigating the potential for using Eagles due to special considerations for them having a $50 legal tender value. If I discover solid benefits for that, I will use Eagles over Leafs, since my Canadian country-hedging is fairly weak due to the fact that gold is gold so it doesn't much matter which country is stamped on there.
