Actually, to a small degree I have a different take. I stick (almost 100%) to the American Eagles, both in silver and gold. I like them because they are STANDARD, in the sense that they are best recognized and they stack well into the US Mint plastic tubes.
A tube of (20) Gold Eagles is almost enough for a "big purchase" (land, machinery, etc.). 5 tubes would equal a 100 oz bar.
A single Silver Eagle will (say) buy a decent load of groceries.
I DO recognize that having "small" silver (dimes, quarters or fractional Silver Eagles <--- do they make fractional Silver Eagles?) for small everyday purchases (say a case of beer..., LOL) would be good. I have not yet acted on this one yet.
I do have a few 1/10 oz Gold Eagles, as they are "halfway", if you will, between a Gold Eagle and a Silver Eagle.

And just in case everything turns out great? That the Green Shoots really do portend a resurgent economy and that we will live happily ever after? That is why I own platinum too. Platinum is for optimists... Increased economic activity means more demand for platinum (as a catalyst).
Diversification means that you have to account for "White Swans" (the good ones) too!
While I would still be completely happy if I only had ASE's as DCRB mentions, I am a still a tad happier with some diversification in silver
It really is hard to go wrong as long as you have some silver and some gold, in whatever format.
For escobar's benefit, here are some bits of info about various types of silver. Please feel free to add info to the list or make corrections if you see any errors below.
Bars - 0.999 silver, low premiums, easiest to counterfeit (?), various sizes, 1 oz, 10 oz, etc.
ASE's - 0.999 silver, higher premiums, very well known, very liquid
90% silver US dimes, quarters, half dollars - 0.90 silver, low premiums (sometimes even below spot), hard to counterfeit, or perhaps not worth the effort to counterfeit (?). Usually sold by the face value. For example $1000 face value of 90% silver contains approx 715 oz of silver. Also referred to as Pre-1965 coins and also "junk silver", but there is nothing junk about these coins.
Generic silver rounds - 0.999 silver, low premiums (for example Buffalo rounds).
Foreign coins (Canadian maple leaf, Austrian philharmonic, etc) - 0.999 silver
There are also 40% silver US coins, but I don't care for those too much.
Oh and stay way from Nickel silver, also known as German silver which is a copper alloy with nickel and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc.
