A collection of dated gold 2-escudo coins of Bogotá, dubbed the Santa Fe Collection, leads Daniel Frank Sedwick’s treasure and world coin auction No. 10, closing live on the Internet in four sessions on Oct. 25 and 26.

One of the standout pieces in the collection is a 1687-G gold “cob” from the 1715 Plate Fleet wreck, which is plated (pictured) in The Practical Book of Cobs (fourth edition).

The coin, cataloged as Krause-Mishler 14.1 in the Standard Catalog of World Coins: 1601-1700 by Chester Krause and Clifford Mishler, weighs 6.8 grams.

The collection contains nearly 100 dated Bogotá 2-escudo cobs, representing more than 50 different dates, showing changes of styles and assayers over the 130 years of their production. The coins in the auction include several “first and finest knowns.”

“The Santa Fe Collection was carefully formed within the past decade with an emphasis on clearly visible dates,” says firm owner Daniel Sedwick. “Misreading partial dates has created much confusion in this series, which this educational collection will serve to clear up.”

The example in the sale is “struck on an exceptionally large flan, allowing for a full date and king’s ordinal in addition to all central detail,” which includes a “choice” full cross and shield, nr to left and ii-g to the right. In “choice high Mint State,” the example does have gray sediment in crevices. It has an estimate of $3,500 to $5,000.

More than 1,400 lots are offered in the sale, including gold, silver and jewels recovered from famous shipwrecks. Also included are ancient and world coins, medals, tokens and bank notes.

Sedwick’s sale also features a wide range of artifacts, many from shipwrecks, among which are several large cannons as well as guns and swords.

A buyer’s fee of 18 percent applies to successful bids, with a 3 percent discount for certain payment methods.

Catalogs are available from the firm and may also be viewed online at the business’s website, www.sedwickcoins.com. Bids are accepted through www.Auction.SedwickCoins.com.
