Welcome to the chip collecting community! This has been an interesting thread, and quite informative. You have a really nice looking chip in that Trop half pie. One thing I would say is that you mentioned it would look good "when I clean it up". Some collectors do NOT like or trade chips which have been cleaned. I think the reasoning is that, like coins, the original dirt is part of the history, and cleaning detracts from the value and may even damage the chip/coin. I personally am on the other side of the fence. I like to carefully clean my chips before I display them. Just personal taste. Good luck and have some fun!
