That’s a small sampling, have just about everything under the sun when it comes to bullion after all variety is the spice of life..LOL
Really like the Mexican gold. Not as much a fan of the US platinum coin, but I'll probably pick an ounce of platinum here or there eventually. Been tempted once or twice by the platinum Britannia. You have a nice collection there. Makes.me feel better about my need to dabble in all sorts of diverse gold coins. And thanks for the advise about gold bars. Personally I do prefer coins. I like the art work on coins, and easier to test on my sigma machine than a bar would be. The only bars that appeal to me are 1 kilo silver bars, but not at today's premiums on silver. If the silver premiums eventually calm down I may pace an order of 4 or 5 kilo bars. To me collecting silver a single ounce at a time seems counterproductive with how cheap silver is. Bars make more sense there.
Platinum is a real good buy right now, would definitely consider an once or two Yeah Mexican GOLD is very HOT !! I have about 7 onces total, three 1 OZ liberates graded MS 70, also just picked up a 50 PESO coin 1.2 OZ, plus some smaller pieces the premiums on Mexican GOLD are pretty out of sight roughly $600 over spot depending on the year some are more feel free to PM me if you have any questions.
Sounds to me like your motivation is more geared toward "collecting" than you'd like to think. From an investment perspective, buying only one type of thing probably isn't as important as some people make it out to be. The important thing is that you pay the correct price for whatever it is that you are buying. Buying things other than US issues isn't a terrible idea, but if you are paying US issue prices for those other novelty-type alternatives, then that is not a good idea. If you like variety, then go for variety. If whatever you're doing doesn't make you happy in the end, then what's the point anyway?
I resemble your remark. However, I disagree with the premise of said videos, and agree with your approach. They are probably true that for most efficient investing you most likely in the US do best by following their advice. However, what about in the meantime? People like you and I who buy numismatically interesting coins get real value in the meantime in terms of enjoyment of viewing and owning interesting coins, a "return" those who own a tube or two of AGEs do not get. So, if you are the type of person who enjoys coins, and is not just a bullion investor, then I think you indeed maximizing your total return by doing what you do!
I've bought any US GOLD. Whether pre-33, Presidential/First Spouse, Commems, etc etc. There is such a wide array of US Gold (silver, platinum) coins. The problem I have is there are two categories for me. (1) the ones that I like the design of and "collect" and (2) I buy simply for the bullion content that I probably don't like the design of - such as all the $5 & $10 modern commems, First Spouses, etc. I haven't strayed into non-US bullion. I've nearly bought Canadian, Mexican and a few others but have been able to stick to US.
I've been taking this tactic with US 90% silver 'bullion', especially the 1980s-present silver dollar commemoratives.
