Hey guys i just got my first walking liberty half dollar and i had a few questions. A lot of these coins have black around the main design wich makes the design stand out (eric jones coins have this) but mine is sthe complete opposite. Unless you hold it in certain positions it it is actually so white that you can barely see the design. Its not a matter of the design being flattened and worn down because it is in great condition its that the coin itself has whitened. Is there any way to get rid of this whitening? I washed the coin with soap and it got a little better but i want it to be even better. Alsoi know this sounds crazy but the mint mark on my walker is a w. Ive never heard of any thing accept a d s or blank but there is a dedinite w and it looks too perfect to be a coincidental scratch. Anybody know how this is possible? And last but not least id love for anyone to just give me some tips on how to care for my coin and keep it in tip top shape. Thanks!!!!!
