I'm 3 years new, collecting coins. I'm not certified but want to be. I've found some interesting coins. This is the latest. It looks like a repunched mint mark. Maybe doubling on the back and date. I just found a woody looking coin. This might be one. But the oddest error I found on this coin, the Lincoln Memorial is wearing a Cap on the upper right corner. Yeahhhh!!! Any feedback would be appreciated.  Thank you.

Hiiiiii!! Oh my gosh I been trying to collect coins. I found this one in my change yesterday. I was wondering how I would sell it if it had any value. I've never seen a coin with a W... Thank you for letting me join, they told me this was the most recognized site to be a part of.
