Q&A: I have a naturally dark (not tarnished) Jefferson nickel. What caused the discoloration? Is it valuable?

The following is excerpted from Clifford Mishler’s Coins: Questions & Answers

Q: I have a naturally dark (not tarnished) Jefferson nickel. What caused the discoloration? Is it valuable?

A: Off-color Jefferson nickels are not uncommon, and are known in hues ranging from smoky blue through deep purple, to black. The discoloration is caused by an incorrect alloy mix containing significantly too much copper. Some collectors are attracted to them, as some prefer toned Proof coins, and will pay a small premium for them.

The discoloration of poor ally mix is more commonly encountered in the bronze cent, taking the form of coins with discernible yellow streaks on the surface or with a distinct yellowish cast. The coin is normally composed of 95 percent copper and 5 percent zinc. As the proportion of zinc to copper increases, the coins become progressively more yellow, until at a ratio of 30 to 70 percent the alloy becomes ordinary brass.

CAG certified the historic provenance of dozens of Space Race collectibles in the December 2022 auction.

Many historic Space Race artifacts from the personal collection of astronaut Michael Collins that have been certified by Collectibles Authentication Guaranty (CAG) are being offered in an auction this month. Bidding is already underway for the Space Exploration Signature Auction presented by Heritage Auctions, which is scheduled for December 15-16, 2022.

Malaysia: New silver Proof and colour coins released for 50th anniversary of the city of Kuala Lumpur

Hover to zoom.

The Bank Negara Malaysia has released silver Proof commemorative coins, which are in recognition of the 50th anniversary of the establishment of the capital city of Kuala Lumpur. 

The obverse side of the coins, produced in silver and Nordic gold, feature images of the Kuala Lumpur skyline and modern transportation juxtaposed against the clock face of Bangunan Sultan Abdul Samad. The buildings shown include, from left to right — the Petronas Tower 3, the Petronas Towers, the telecom tower, and Kuala Lumpur’s most recent addition, the Merdeka 118. Distinct with its multi-faceted diamond-shaped façade and unique spire design, it is now the second-tallest skyscraper in the world at 679 metres (2,227 feet) tall. The positioning of the skyline against the clock face symbolises the passage of time since the granting of city status to Kuala Lumpur in 1972, which saw the city progress and develop into a modern city. The text JUBLI EMAS BANDAR RAYA KUALA LUMPUR...
