Other than not been considered a numismatist. I am still interested in learning about coins. I saw this thread http://www.cointalk.com/t207475/ and it got my attention. I didn't want to highjack the thread to ask my question so I started this one. I have never heard of "date palms" before. Now I am curious to learn as to why they are called that. Are certain palms, shown on the coins the date on them or what. I would like to be educated as to why such a term is used and are they highly collectible?
