In the vocabulary term series under U.S. Series it states that Charles E. Anthon was president of the Numismatic and Antiquarian Society of Philadelphia. This is not correct. Professor Anthon was president of the New York Numismatic and Archaeological Society. He died in 1883. The president of the Philadelphia society was Eli K. Price. He died in Nov. 1884.

I would like to comment on the bio. of Marshall Lefferts, As usual John Lupia does a great job in providing us with information on 19th and early 20th century collectors. this information is really a history of numismatics in America. Thank you, John.

Lefferts had a fine collection. It is rated a B+ by Adams. He was still a young man when his collection was sold in 1881. I wonder why he stopped collecting coins? Perhaps his marriage and having two young children took all his spare time.

I really appreciated the item and link about Niobium. It took me way back to the beginning of my career working in a materials analysis lab. We had a request to test for the percentage of Niobium in a sample. Nobody knew how to do it so it was given to me, the newest guy, to figure out.

This was before the internet so I had to turn to my college textbooks. Once I figured out that Niobium was called Columbium when I was in school it got a lot easier. Of course my textbooks were newer that the older guys books and had that name change information in a footnote. That was a nice feather in my cap that year. Good memories!!

Thanks for posting the interesting material on the “Janus Head” copper. I’ve always wondered - though not enough to attempt any original research on the subject - why a three-headed coin is called “Janus.” I guess that is cleared up. As to the 1/2D inscription, I was under the impression that the denier/denarius symbol was always a lower case d. And I was always under the impression that £, s, d stood for livre, sou, denier in French, not the Latin.

Kraljevich’s piece in the supposed Continental dollar was fascinating as well.

The British coin which is the same size as a golf marker is the 5p. For several years the Isle of Man acknowledged the fact and issued five pence coins with golfing themes on them; below, 1994-95 on the left and 1996-99 on the right.

The obverse showed a standard portrait of the Queen with inscription and date. I have no idea whether anybody actually told her that her image was regularly stamped into the ground by golfer's feet so that she could be putted over cleanly without diverting the ball.

I believe that one of the ball markers that Dave Klinger shows is really a guitar pick (Although I guess it could be used as a ball marker).

The Royal Canadian Mint has Escaped from Reality in this UFO issue and brought themselves down to the level of minor states and Australia which mint coins and stamps as a business. Will it sell is the only criterion. Numismatics should ignore these products and not even catalog them with regular circulating coins. Like Unusual Coins maybe the NCLT should have a separate catalog in the SCWC series and make the main catalog of manageable size. They have it for SCWPM as specialised issues.
