I agree the technology to put such detail in a mass-produced coin which is just 3 mm in diameter is great. Maybe the R&D & Marketing cost US$200,000, which justifies the Swiss Mint charging 999 coin collectors US$205 for US$3 worth of Gold & Packaging. A previous record holder over 600 years old is shown in

The 1/10th Fanam Gold coin called Bele with a size around 2-4 mm and weight around 0.04 grams is also smaller than the modern Swiss coin.

I was already familiar with the famous picture of Einstein sticking out his tongue. I often wondered at whom he was sticking it out. Now I know! Since it occurred on March 14, 1951, he was sticking it out at me because that is the day I was born. I guess he didn't like me.

I received my third Great Micromosaic Passion coin last week (The Girl with a Pearl Earring). It is really outstanding.

"I can’t be entirely sure of everybody in the Smithsonian photo, but I easily recognize the Stefanellis. I am pretty sure that is Hans Schulman at the far left. The person seated across from Mrs. S is definitely not Abe Kosoff."

"In the article about Don Hirschhorn, Dave Lange has asked for a photo of him at a younger age. This one shows Don on the right and R. S. Yeoman on the left."

Illustrated here is the storefront of Burdette G. Johnson’s St. Louis Stamp & Coin Co. in 1915, taken from the December issue of Philatelic West for that year. Johnson, operating at 115 N. 11th Street in St. Louis, frequently advertised stamps, coins, and other collectibles in the pages of Philatelic West. The image is grainy, but conveys the essential information. The downtown city lot is narrow, with a large display window and a door to the side. An awning provides some protection against the elements when entering or exiting. We can only speculate what was on display, but it was likely some combination of coins and stamps with a few other objects mixed in.

Who is the man pictured on the right and what is his role in current numismatics?

"I thought some readers might be interested in this year's ANA Summer Seminar and the class I will be teaching with David Alexander. We will be reprising the Survey class covering medals from the early portrait medals of the Renaissance to contemporary medals issued in the 21st century. The course will cover technical aspects of producing medals, important references and literature. and an historical survey encompassing major periods, styles, countries and important artists and engravers. The course will include much new material added since the last survey course in 2016. More information can be found on the ANA website."

Check out this find at a wine store near me this past weekend. Mercury Head Cabernet. Really high star rating, but also really expensive. I couldn't help myself and had to buy it. (Then explain to my wife when I brought it home that this nice wine is NOT for drinking!)
