The story says this coin sold for $600,000 in 1981, and $3,000,000 a
couple of days ago, and that "coins sometimes appreciate at an
extraordinary rate."

The doubloon appreciated in value by about 6.9% per year.

The Dow Jones Industrial Average was about 970 in 1981, and about 10,500
today, so it has appreciated at about 10.4% per year.

Put it another way: $600,000 invested in blue chip stocks in 1981 and held
there would be worth about $6,500,000 today.

These numbers are not quite accurate. The Dow Jones index is a managed
index. Companies that are part of the index get replaced by new companies.
Doing this with your stocks incurs cost, doing this via a mutual fund also
incurs cost. The above analysis of present value investment is the
'smokescreen' used by those that make money with investment services. Had
to put my 2 cents as I paid 2% for mutual fund service charges for too many
years and thus not getting the 10.4% per year you mention.

Also, I suspect that any valuable coin collections must be insured, again
cost that makes the 6.9% per year a lot less attractive. How much does a
collection cost to be insured, relative to it's value? 1%, 5%, 10%?
