Potential
Investing in rare coins could make a huge return. A collection bought in the early 1950s by collector Harold Bareford for $13,832 sold for $1.2 million in 1978 and set off a coin collecting craze, according to Austin Rare Coins.

This moved people so much it became required on coins thereafter, according to Coin Collecting Guide for Beginners.
