DALLAS, TX.- An exceedingly rare Russian 10 Roubles coin will land in a new collection when it is offered in Heritage’s CSNS World & Ancient Coins Platinum Session and Signature® Auction April 29-30. An exceedingly rare Russian 10 Roubles coin will land in a new collection when it is offered in Heritage’s CSNS World & Ancient Coins Platinum Session and Signature® Auction April 29-30.

The Nicholas II gold Specimen Imperial of 10 Roubles 1896-AГ SP61 PCGS is an extraordinary coin in a high grade, even rarer than originally believed.

“This is a magnificent coin, one that immediately assumes a prominent place in any collection,” says Cris Bierrenbach, Vice President of International Numismatics at Heritage Auctions. “Both Krause and Bitkin reported an original mintage of just 125 pieces, but the combined census populations at PCGS and NGC include only a handful of certified pieces. That could mean the original population was smaller than initially reported, or perhaps several specimens were lost, melted or otherwise disposed of. But the definite conclusion here is that this auction represents a rare opportunity to acquire an absolute trophy among Russian coins.”

Also offered is one of only four known examples of a rare Philip II gold Cruzado (400 Reais) ND (1598-1621) L-B XF45 NGC. Between the angles of the crosses are five dots — it is more common to find just one — making its reverse an unlisted die variety. The Cruzado denomination is one of the many that fell subject to reevaluation during its time in circulation. During the reign of King João III, the cruzado increased from 400 Reais to 500 Reais, but eventually reverted back to the base value in 1584 under King Philip I, under whom the production of the two and four cruzados began. The reverse design of the cruzado also changed, with the cross of Christ becoming the cross of St. George, which is what is presented on the specimen offered in this auction.

Part of the intrigue surrounding an Elizabeth II gold Proof Sovereign 1957 PR65 NGC centers on the fact that it was produced for just one year. Due to post-war austerity measures, no gold coins were included in the Queen’s Coronation set released to the public, with only a small number of 1953 Coronation gold coins presented to high-ranking officials and institutions to mark the occasion. Sovereign 1957 Proofs are incredibly rare, with estimates ranging from 11 to 20 known pieces.

A Victoria Proof “Gothic” Crown 1847 PR63 Ultra Cameo NGC comes from a type already coveted by serious collectors, but the example offered in this auction is part of a limited subvariety, struck in pure silver with a plain (unlettered) edge.

The auction also features important collections, including the Otoh Collection of Physical Cryptocurrency, Part VII — an exceptional installment in what has become one of the most important offerings of physical cryptocurrency artifacts ever assembled.

Among the highlights is a Pernambuco. Dutch Colony - Geoctroyeede West-Indische Compagnie (GWC) gold Klippe 12 Guilders (Flor… that is a magnificent example of a coin that is the largest denomination and among the most attractive examples of this Dutch-Colonial issue of the first coins ever struck in Brazil. During the period of Dutch colonization of Brazil (1630-54), three gold Klippe denominations — of 3, 6 and 12 Guilders — were minted in the Captaincy of Pernambuco for use within Brazil, beginning in October 1645. But these issues were not legal tender in the Netherlands, and thus any such pieces that reached Europe were exchanged for Dutch Guilders and subsequently melted. In addition, any such pieces remaining in Brazil after 1654, when the Dutch were finally ousted from South America, would have been melted, as after this period any Portuguese or Brazilian found with a Dutch coin ran the risk of being considered a traitor and hanged — a consequence that made the survival of such pieces at all extremely uncommon.

Another key cryptocurrency offering is a Kialara silver Unloaded (Unfunded) “To The Moon” 0.5 Bitcoin (BTC) Cold Storage Bar 2017 Genuine PCGS. Introduced in 2014, Kialara pieces were conceived as a fusion of art and security, ingeniously designed so that the private key remains inaccessible without destroying the object itself, encouraging long-term stewardship much like a modern digital piggy bank.

Complementing this highlight are the striking Kialara Builders — Emerald eyes, two coveted Kialara OG notesand a singular Kialara Guardian round, a captivating work demonstrating the innovative integration of AI-assisted artistry within the Kialara universe.

Another collection in the auction is the Vila Rica Collection of Brazilian Gold Coins, Part I. The consignor spent more than three decades forming a comprehensive record of Brazilian gold, silver and copper coinage. The silver portion of the collection was offered at Heritage in May 2021, and the gold offered in this auction marks the first installment of a three-part offering that begins with early Dutch-Brazil siege coinage and continues through the first official mint emissions of Brazil, beginning in 1695 and extending through the final issues of João V. Future selections from this extraordinary cabinet will continue at Heritage’s ANA U.S. Coins Signature® Auction September 2-6, 2026 and NYINC 2027, where additional gold rarities will be offered. Complementing these sales, select copper issues from the collection will be presented in partnership with Vila Rica Moedas in June 2026.

Among the highlights is a Pernambuco. Dutch Colony - Geoctroyeede West-Indische Compagnie (GWC) gold Klippe 12 Guilders (Florins) 1646 MS61 NGC that is a magnificent example of the largest denomination of that is among the most attractive examples of this Dutch-Colonial issue of the first coins ever struck in Brazil.

• A Pernambuco. Dutch Colony - Geoctroyeede West-Indische Compagnie (GWC) gold Klippe 3 Guilders (Florins) 1646 AU55 NGC

• A Pernambuco. Dutch Colony - Geoctroyeede West-Indische Compagnie (GWC) gold Klippe 6 Guilders (Florins) 1646 AU Details (Cleaned) NGC
