If I may...
I am a bullion collector by accident. Investing in coins for hard times. To keep the boredom low, purchasing different bullion is interesting. Krugerrands, Maples, Eagles, Britannias, Nuggets, Philharmonics, Isle of Man Angels/Cats/Dogs

, Pandas, Libertads, Ducat restrikes(government issues of gold coinage produced as bullion), Buffalos, French Angels

/Napoleans(produced in vast numbers and trading like bullion)... Then there are all these 1/20 & 1/25 commemoratives; Nuie, Tuuvalu, Mariannas Islands, etc. etc... commemorating everything from Einstein to the Pyramids(no need for the subject to actually represent the producing country)

. I certainly am not interested in them all, but always try to get something different, but marked as to it's gold content.
So, as an investment you can still make it interesting. It is possible to get stuff near spot(say, no more than 4%) with shipping on
ebay... I lose a lotta auctions. But, if I won them all I'd also not be happy... I'd be downrite poor!

Starting with the major recognized coins(Krugerrands, Maples, Eagles, Britannias, Nuggets) you can buy fractionals to suit your budget, but buy as bullion... let them get away if too costly, there will be more upcoming. If you buy in your own country, no problem, if you are importing you must learn about import regulations. The fact that some coins carry a token monetary value reflects greatly on import duties and excise. The country of origin for any trade recognitions(regardless of where the coin is sent from) is also a factor.
But enough of all that...

There are proof bullion coins and sets that are considerably over spot. The
RCM produced a $2 plain bullion finish coin(to reflect Canada's circulation twoonie coin); 1/15oz gold maple in 1994, with a mintage of only 3,540. They can be worth several hundred$.

Maples are also privy marked in certain years... a little fireworks mark for year 2000... family, eagles, liberation, viking ship(rare,collected,expensive). Then there are proof strikes, anniversary issues, coloured sets, hologram sets, ringed(silver) bi-metallic... yes, these are all maples.
1979 - 1982 .999
1982 - present .9999 with experimental .99999; these go for around 50% more than bullion.
The design has changed as well. Minor stem, relief changes. And wording changes.
Again, I digress. There are collectable bullion coins that go for well above spot... you may get lucky buying bullion.
