As to the gold coins then five specimens are found in the 1793 catalogue, and the two oldest coins are mentioned in the 1681 manuscript catalogue of the collection of gold coins of King Christian V (1670-99), which was preserved at Rosenborg 4 . A third gold coin is mentioned in the addenda of another copy of the same inventory, probably added с. 1728 5 . Gold coins present in the Royal Collection 1793 1. Christopher Báthory, 10 ducats 1577, Resch no. 2, 35.31 gr. (already present 1681) 2. Gabriel Bethlen, 10 ducats 1616, Resch no. 12, 34.52 gr. (already present 1681) 3. Michael Apafi, 10 ducats 1670, Resch no. 79, 33.83 gr. (mentioned с 1728) 4. Michael Apafi, 5 ducats 1673, Resch no. 127, 17.21 gr. 5. Charles VI, ducat 1733, Resch no. 55, 3.47 gr. Besides too gold coins from the collection of the last absolutist monarch Christian VIII (1839-48) are found. They may be mentioned here, because the heayer one of them apparently is unique (not mentioned in Resch) 6 . It is a ducat (3.49 gr.)and a 1 1 / 2 ducat(5.20 gr.) issued on occasion of the proclamation of Ferdinand I in 1837 in Sibiu (Hermannstadt/Nagyszeben). Together with a silver coin they entered the collection of the heir to the throne —may be the till now unknown V/ 2 ducat was distributed to persons of less prominent position than actual heads of state ? Apart from this rather recent piece then the 10 ducats of Gabriel Bethlen may be the most interesting specimen, because it perhaps was a gift from Gabriel Bethlen to his DanishNorwegian ally Christian IV (1588-1648). We know there were diplomatic negotiations between a representative of Gabriel Bethlen and the Danish-Norwegian king in 1627 in connection with a planned alliance against the Emperor 7 . May be the gold coin was a small present from the Siebenbürgen negotiator Matthias Qvad de Wickrad at some time during the negotiations? 4 Konning Christian Den Femtes Guld-Medailler, Inventory 20 March 1681 (Royal Collection of Coins and Medals, National Museeum, Copenhagen), under the head-lines "Ungerske, Burgundiske, 0sterrigske og Sibenburgske". 5 Mentioned in an addendum to a final version of the above-mentioned inventory. 6 A.
