Enormous Gold Coin Certified by NGC Leads Part 5 of SINCONA British Collection Auctions

Posted on 10/17/2023

The 5-kilogram coin is among the largest and most valuable coins ever struck by Great Britain and will sell for hundreds of thousands of dollars in the October sale.

An impressive modern rarity with 5 kilograms of gold is among over 500 coins certified by Numismatic Guaranty Company® (NGC®) that are part of an upcoming SINCONA auction. Bidding is already underway for SINCONA Auction 86, the fifth and final part of the SINCONA British Collection, which will be held on October 24, 2023.

The auction's top highlight is a Great Britain 2019 5 Kilogram Gold £5,000 Una and the Lion graded NGC PF 69 Ultra Cameo (lot 1845), which has a starting price of 350,000 CHF (about $385,000). This unique coin helped inaugurate a new series from The Royal Mint that celebrated "The Great Engravers" and their work that has graced British coinage for centuries. This coin shows Queen Elizabeth II on the obverse and the venerable "Una and the Lion" design on the reverse. This timeless work of William Wyon was first issued in 1839 on a 5 Sovereign coin that celebrated the young Queen Victoria.
