The Wikipedia article of the day for December 22, 2019 is Maryland Tercentenary half dollar.
The Maryland Tercentenary half dollar was a commemorative fifty-cent piece issued by the United States Bureau of the Mint in 1934. It depicts Cecil Calvert, 2nd Baron Baltimore, on the obverse (pictured) and the coat of arms of Maryland on the reverse. The Maryland Tercentenary Commission sought a coin in honor of the 300th anniversary of the arrival of English settlers in Maryland. The state's senators introduced legislation, and it passed both houses of Congress with no opposition. A design had already been prepared by Professor Hans Schuler; it passed review by the Commission of Fine Arts, though there was controversy over whether Lord Baltimore, a Cavalier and Catholic, would have worn a collar typical of Puritans. The Commission sold about 15,000 of the full issue of 25,000 for $1 each, and thereafter discounted the price for large sales to dealers and speculators. The coins have increased in value over time, and are now valued in the low hundreds of dollars.
