Opened in 1713, the Gotha Coin Cabinet at Friedenstein Castle was one of the largest and most important coin collections in Europe in the 18th and early 19th centuries. Marked by a varied history until recently the numismatic collection felt the consequences of the Second World War. Although the coins removed to the USSR in 1945 were returned already in 1958, over 16,000 of the most important pieces in the collection were still missing. Most of these were ancient coins brought to Coburg by the ducal family as a precautionary measure and returned to Friedenstein in 2011. The collection now consists of 145,000 numismatic objects, from antiquity to modern times. They are to be digitised and made available online in the shortest possible time thanks to the “Gotha transdigital2027” project. A brief insight into the innovative approaches used in digitising this important collection will be given.
