Mine is an 1870 3 cent piece in PR65 Cameo, mintage 1000. I'm a special snowflake. Price guide is only $1250... What? (04082003 d/m/y) My dad's birthday resulted in an MS-70 First Strike 2010 Silver Eagle.
If I had your real name, I could find your birthday without you telling me. At least, if you have ever had a credit card, been issued a driver's license, or a host of other things. It's pretty hard to remain off the grid in the 21st Century.
