How to Price Your Coins: Sold Prices vs Asking Prices vs Price Guides
Sold prices, dealer asking prices and price guides each tell you something different about what a coin is worth. Here's which one to trust, and when.
Ask three people what a coin is worth and you’ll often get three answers. One looked up a price guide, one saw a dealer listing, and one checked what the coin actually sold for. All three numbers are real. They just measure different things.
Here’s how to tell them apart, and which one to lean on when you buy, sell or insure.
Sold prices: what buyers actually paid
A sold price (also called a realized price) is the strongest evidence of value because money changed hands. You’ll find them in:
eBay sold listings (filter by Sold Items)
Auction archives from Heritage, Stack’s Bowers, GreatCollections and others
The PCGS Auction Prices Realized database for PCGS-graded coins
Two things to watch. First, auction results usually include a buyer’s premium on top of the hammer price, so compare like with like. Second, one sale is an anecdote. Look for three or more recent sales of the same coin before you call it a value.
Asking prices: what sellers hope to get
Dealer websites, Buy It Now listings and show tables show asking prices. They’re useful for knowing what you’d pay if you bought right now, but they aren’t proof of value. Plenty of listings sit for months because the price is too high.
When there are no recent sales, asking prices are still a fair starting point. A common rule of thumb is to treat the lower end of current asks as the ceiling for a realistic sale.
Price guides: a reference, not a sale
Price guides like the PCGS Price Guide, the Red Book and the Greysheet pull together dealer and market data into one number per grade. They’re great for a quick sense of scale and for spotting whether a coin is a $20 coin or a $2,000 coin.
The catch is that guides lag the market and average things out. The PCGS guide, for example, reflects average dealer asking prices for PCGS-graded coins. The Greysheet reflects wholesale prices between dealers. Neither tells you what your specific coin sold for last week.
Why the exact match matters
Coin value turns on small details. A comp only counts if it matches on:
Date and mint mark: a 1921-D Morgan is not a 1921 Morgan.
Grade: MS63 and MS65 can be worlds apart.
Grading service: PCGS and NGC coins often trade at different levels, and raw coins trade lower still.
Variety and designation: DCAM, VAM varieties, full bands and CAC stickers all move prices.
A “close enough” comp is how collectors overpay and dealers underprice.
A simple pricing routine
Identify the coin exactly: date, mint mark, grade, service, variety.
Pull sold prices from the last 90 days. If there are none, widen to 12 months.
Check current asking prices to see where the market is heading.
Use a price guide as a sanity check, not the final answer.
Write down the date you priced it. Values move.
Keep your prices current without the busywork
Doing this for one coin is easy. Doing it for 500 coins every few months is where spreadsheets break. Kilito pulls recent sold results and current listings for each coin in your inventory, filters out the bad matches, and labels every value as Confirmed or Estimate so you know how much to trust it.
