How it works

From auction photos to a max bid on every lot.

Every kind of auction: coins and bullion, gold, jewelry and watches, sports cards and collectibles, antiques and art, cars and trucks, boats and trailers, farm equipment, construction and heavy equipment, tools and machinery, estate and household, real estate, and government and surplus sales. New England today, and any auction online by request. You get a printable PDF bid book plus a workbook, before preview day.

    Standout items in the photos are flagged.

  4. 04

    Comparable sales

    Melt, comparable-sale and realistic sell values for each item, with full sold comparable sales on key lots and Professional Coin Grading Service (PCGS), Numismatic Guaranty Company (NGC) and Professional Sports Authenticator (PSA) certificate lookups.

  5. 05

    Max bid

    A max bid per lot after the buyer's premium and Connecticut sales tax where it applies, using our standard margin (want a different one? just tell us).

    CHASEMAYBECHECK FLOORSKIP
CHASE

A lot worth going after, up to the max bid. Sold comparable-sale links included.

MAYBE

Worth a look at the right price. Sold comparable-sale links included.

CHECK FLOOR

Needs an in-person look. On the preview-day checklist.

This is an estimate, not an appraisal.

Max bids are a ceiling, not a target.

Why you can trust the numbers

Checked, then checked again.

Multiple confirmed checks

Every key value and max bid is confirmed by at least two independent sources. The book shows the check count, and lots with fewer than two are marked low confidence.

Sold comparable sales you can open

Full sold comparable sales on key lots, with sold comparable-sale links on every CHASE and MAYBE lot.

Preview-day checklist

A checklist for every CHECK FLOOR and low-confidence lot, so you know what to look at in person.

Certificate lookups

PCGS, NGC and PSA certificates looked up on graded items.
