I'm sure this has never happened to you.

Here I am trying to save up for an 1893-O S$ in ms63, which for me is a very pricey coin, and I found one at an excellent price, but wait....I find an Indian Head cent for only $$$ and then a Barber quarter for $$$, etc. Then I remember all of the 'good buys' that got away. I know that coins just as nice will come up again and probably before I can afford them. What is a numismaniac to do?

Happy hunting all.
