Building Coin Dealer Inventory on a Budget

What to Stock: Building a Balanced Inventory

Your inventory is your business's most important asset — it determines what you can sell, how much revenue you can generate, and what kind of customer base you attract. A well-constructed dealer inventory balances several factors: breadth (enough variety to attract diverse buyers), depth (enough stock in your specialty areas to be a credible source), turnover speed (coins that sell within weeks, not years), and margin potential (adequate spread between your cost and selling price).

Start with what you know best and what sells consistently:

Silver bullion — American Silver Eagles, pre-1965 90% silver coins ("junk silver"), and silver rounds. Bullion is the bread and butter of many dealers because it sells constantly, pricing is transparent, and customers range from first-time buyers to experienced investors. Margins are thin (2–8% typically) but turnover is fast. Every dealer should carry bullion regardless of their numismatic specialty.
Gold bullion — American Gold Eagles, Buffalos, and foreign gold coins (Krugerrands, Maple Leafs). Higher per-unit value means more capital tied up but also larger dollar profits per transaction. Essential for attracting serious buyers.
Popular US type coins — Morgan dollars, Walking Liberty halves, Mercury dimes, Buffalo nickels, Indian Head cents, and Barber coinage in a range of grades. These are the series that the broadest segment of the collecting public actively seeks. Stock a range of grades from Good through Mint State to serve buyers at every budget level.
Certified coins — PCGS and NGC graded coins in your specialty areas. Certified coins sell faster and at higher margins than raw coins because buyers have confidence in the grade. As you build capital, shift your inventory increasingly toward certified material.
Supplies and accessories — 2x2 holders, flips, albums, loupes, and reference books. Low margin but high turnover, and they bring customers to your table who may then buy coins.

Sourcing Inventory

Acquiring inventory at prices that allow profitable resale is the core skill of coin dealing. Major sourcing channels:

Walk-in sellers at shows — People walking the show floor looking to sell collections, estates, or individual coins. This is one of the most profitable sourcing channels because you are the first buyer the seller encounters — no competing bids. However, you must evaluate coins quickly and accurately under show conditions. Prominently display a "WE BUY COINS" sign at your table.
Other dealers — Dealer-to-dealer trading at shows is a major inventory source. Dealers buy from each other at Grey Sheet wholesale prices, then retail to collectors at markup. Building a network of trusted dealer relationships who know your buying interests is essential for maintaining fresh inventory.
Auctions — Heritage, Stack's Bowers, and GreatCollections auctions provide access to individual coins and collection lots. Auction buying requires discipline — it's easy to overbid in the heat of competition. Set firm maximum bids that allow adequate retail margin after buyer's premiums (15–20%) and grading/attribution costs.
Estate and collection purchases — Buying entire collections from estates, retiring collectors, or their heirs can be highly profitable. You acquire diverse inventory at bulk wholesale pricing. However, large collection purchases tie up significant capital and may include material you don't specialize in (which you'll wholesale to other dealers at lower margins).
Coin roll hunting and circulation finds — At the early stages, some dealers supplement inventory with circulation finds. This is time-intensive but requires zero capital and occasionally produces surprisingly valuable coins.

Inventory Management

As your inventory grows, systematic management becomes essential:

Track every coin — Record the date acquired, cost, source, description, grade, and asking price for every coin in inventory. A spreadsheet works initially; dedicated software (QuickBooks, specialized coin dealer software) becomes necessary as inventory scales.
Know your cost basis — For every coin in your case, you should know instantly what you paid and what your minimum acceptable selling price is. This prevents selling coins below cost in the heat of a show transaction.
Monitor aging inventory — Coins that sit unsold for more than 6–12 months tie up capital that could be generating turnover in fresher stock. Be willing to wholesale aged inventory to other dealers at reduced margins to free up capital.
Maintain fresh stock — Regular customers visit your table expecting new inventory at each show. If your stock looks the same show after show, they stop visiting. Active sourcing and inventory rotation keeps your table interesting and customers returning.
