Okay, at the risk of messing up the thread, the coolest "coin bowl" I have is this Scottish "Quaich" - a vessel for drinking whiskey out of. They still make them, and they are still used for ceremonial occasions (weddings, etc.): This is a Scottish quaich, a drinking vessel, made by Wilson & Sharp in Edinburgh in 1900. It is sterling silver. The coin in the bottom is an English sixpence of King Charles II dated 1668. The maker mark is a "W & S." The hallmarks are as follows: thistle silver standard mark (indicates .925 sterling silver); castle (indicates Edinburgh manufacture) and a Gothic "t" (indicates 1900 manufacture date). I got it on eBay - one of those "I don't know what this is" auctions - I didn't know what it was either, but I liked the coin.
Until today I would have bet good money that I was the only weirdo that liked/wanted these. I can't believe there are 3 people on CT that have some version of these. Sorry to the OP for messing up his thread.
This is the best one in the thread, for me. Described by Ernest Bramah in his 1929 book "English Regal Copper Coins" it does not have the stop after REX (Bramah 11a). I have one of these too, but sadly it's lower grade and a lot lumpier round the edges than yours: It has other characteristics such as the missing lower serifs in III, and the broken D in D:G Mr Bramah has this to say: Yours is only the third one I've seen. Nice buy.
Back on topic, I recall holding a splendid Red UNC Cartwheel 2d at a big national show, once. It might have been at the Spink table. I forget. Might've forgotten the dealer, but not the coin. That one made an impression.
