I noticed this was your very first post treasure778 - so, Welcome Aboard! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).
Not rare, but as a collector, if you live in the Midwest or out East, its always nice to find a coin with the S mint mark. With the coin being minted in San Francisco they mostly stayed out on the West coast.
