Services

• Auctions and Direct Sales Specialists in Spanish colonial, Latin American, and shipwreck coinage, including gold, silver, ingots, and related artifacts, as well as select world coinage from the sixteenth century to modern issues. We conduct floor and online auctions and also offer material directly through our webstore and in person. Every consignment is carefully attributed, cataloged, and positioned for strong results. We maintain direct relationships with advanced collectors worldwide and personally notify the appropriate clientele when material of their interest becomes available. When suitable for auction, we coordinate submissions to NGC or PCGS, properly noting variety and rarity, with efficient turnaround and added value at sale. In select cases, professional conservation may be performed for auction consignments, particularly shipwreck material, to improve presentation and performance. 

• Certificates of Authenticity Formal Certificates of Authenticity are available for qualifying material under current submission guidelines. Each certificate is saved in our database and will be dated, signed, embossed and also marked with a holographic unique sticker by Sedwick & Associates, LLC. Please consult our posted Certification Fee Table for current costs and policies.

• Appraisals and Cataloguing Professional appraisals and cataloguing services for collections and estates, prepared with the same standards required for insurance, estate planning, or future sale. Fees vary according to scope of work.

• Auction Commission Bidding and Representation We represent clients at major numismatic auctions in the United States and worldwide. Lots are inspected carefully, rarity and condition are evaluated in person, and bidding strategies are structured to secure important material without unnecessary risk. All bidding is executed discreetly and professionally.

• Collections Development Important collections are built with discipline and focus. We help collectors define goals, establish quality standards, and pursue key pieces that add depth and distinction. Guidance is based on experience, careful study, and market awareness, resulting in collections with coherence and lasting significance.

• Professional Collection Assessment A thorough evaluation of significant private cabinets addressing historical attribution, rarity and die variety classification, census research, and documented pedigree. Each collection is placed within recorded auction history and standard references. Reserved for important collections, not single coins. We review structure, strengths, redundancies, and market position, identifying practical steps to refine and strengthen the cabinet. When needed, XRF analysis may support authenticity review. Documentation is prepared in clear auction catalogue format to support long term value.

• Professional Conservation Offered only for selected auction consignments and when appropriate for the material, always with strict respect for originality and surface integrity.

• Publishing and Editorial Support We have published and collaborated as editors on major numismatic references. When the subject and work merit it, we can assist collectors and authors in bringing research to publication with careful editorial standards and quality printing.

• Digital Photography Professional high resolution digital photography for auction consignments, private collections, and research publications. Each piece is imaged with attention to accurate color, surface quality, and relief detail, suitable for auction catalogues, certification records, insurance documentation, and long term archival use.

Experience, discretion, and careful market judgment define every consignment and advisory engagement.

 

Note: We are always pleased to provide auction estimates for potential consignments and to consider direct purchase offers. However, under our current policy, we are unable to comment on material offered by other sellers, discuss third party pricing, or advise others on how to price coins for sale.
