In Germany, the numismatic year begins with the World Money Fair, kicked off by our Auction Sale. What happens there sends an important signal. The prices achieved this year demonstrate that the market appreciates rarities, delivering high results. 694 lots with a total estimate of 6 million euros were on offer. The total hammer price of the auction was 9.5 million euros (excluding buyer’s premium!), approximately 60% more than the total estimate.

Top 3: Two Coins Fetched a Hammer Price of 140,000 Euros

By now, it goes without saying that multiple gold coins are extremely popular with numismatic investors. This is proven once again by a 10-ducat coin from Nuremberg, distinguished by its sharp minting quality and its perfect condition. Dating from 1630, the piece is extremely rare. One side shows a winged putto standing frontally and holding the small and the large coats-of-arms of Nuremberg in its hands. The other side is dedicated to Ferdinand II. He is depicted in full regalia, with crown, scepter and coronation cloak, on a rearing horse. 1630 was the year of his greatest power. Wallenstein had just secured him a resounding victory in the Thirty Years’ War, leading the emperor to believe that he could reclaim all the possessions of the Catholic Church via the Edict of Restitution. However, he had overplayed his hand. When Gustavus Adolphus landed in Peenemünde on Usedom on 6 July, the Protestants welcomed "the Lion from the North" as a liberator and the course of the war changed. Künker’s experts had estimated the piece from the Erlanger Collection at 50,000 euros. Their comment stated that this coin had been minted using the modified die of the 1628 double taler. The year was changed to 1630, and the metal specification from ARGENT to AVREA*. The rarity was sold for 140,000 euros plus premium and taxes.

A 1651 five-fold reichstaler bearing the portrait of Ferdinand III, minted in Kremnica, saw an even greater increase in value. It jumped from an estimate of 30,000 euros to almost five times that amount, reaching 140,000 euros – although it does not align with the preferences of today’s investors. After all, it is “only” of very fine quality. However, it is a magnificent and extremely rare coin. Werkner knows of only two other specimens: one in the Budapest coin cabinet and one in the Montenuovo Collection. The result proves that collectors in neighboring Czech Republic and Slovakia appreciate rarities, even if they are not of perfect quality. This was demonstrated not only by this result, but by all lots involving a mint that is now located in the Czech Republic.

For example, a broad double reichstaler from Prague dated 1610 jumped from an estimate of 7,500 euros to a hammer price of 95,000 euros. You got that right. Despite a slightly weak strike on the portrait side and its very fine quality, the specimen fetched more than twelve times its estimate. The other results for coins from the Prague mint show that this sum was not an exception. A 1615 ducat, albeit of extremely fine quality, rose from 10,000 euros to 44,000 euros; a 1630 reichstaler increased from an estimated 7,500 euros to a result of 60,000 euros.

Let us give one last example to illustrate the strength of the Czech market and the expertise of Czech collectors: a broad double reichstaler from Kutná Hora sold for twelve times its estimate of 5,000 euros – a remarkable 60,000 euros. Incidentally, Kutná Hora was one of the most important Czech silver cities, supplying the silver for the famous Prague groschen. Around 1600, it was the second most important and populous city in Bohemia after Prague and had its own mint.

Top 2: 200,000 Euros for a 20-Fold Ducat of Leopold I

A 20-fold ducat of Leopold I in about extremely fine quality sold for exactly the estimated price of 200,000 euros. This piece was minted at an unknown date during Emperor Leopold I’s reign from the dies supplied by engraver Maximilian König in 1666 for a fee of 200 gulden. These dies were used to produce coins of 50, 30, 25, 20, 18, 15 and 12 ducats. These coins were not only commissioned by the emperor himself, but could also be commissioned by private individuals, as long as they had obtained imperial permission, supplied the mint with the necessary gold and covered the minting costs. This means that it was not only the emperor who used these coins as diplomatic gifts. For example, we know that in 1699, the emperor’s wife had two off-metal strikes with a weight of 20 ducats minted for her own purposes, and that, in 1670, court councilor Johann Franz Freiherr von Kaiserstein was granted permission to mint 15- and 20-ducat coins at his expense. Incidentally, attempts were also made to produce 10-ducat coins with these dies. However, this was unsuccessful as the blanks were so thin that the relief of the minting was no longer clearly visible.

Top 1: 220,000 Euros for a 1712 Ducat of Peter I Graded MS61 (Top Pop)

Russia continues to set record prices, as demonstrated once again by the most expensive item at this auction. This extremely rare ducat of Peter I from the Red Mint in Moscow was graded MS61 by NGS, the highest grade in the entire series. The classic design features a portrait of the tsar with laurel wreath, armor and military cloak on the obverse, and on the reverse the Russian double-headed eagle with the tsar’s crown, on its chest the old Moscow coat-of-arms depicting St. George slaying the dragon. The estimate had been 50,000 euros. The final result was almost four and a half times that: 220,000 euros.
