How your coin offer is built

Coins are the one category where selling to the wrong buyer costs the most, because two coins that look identical can be worth ten times apart. So the order of operations matters: rarity is checked before metal, never the other way round.

1. Read first. Date, mint mark, type and condition on every coin. A common bullion piece and a key date can sit in the same tube; weighing the tube would cost you the difference.

2. Metal value is the floor. Bullion and common-date silver are valued on their actual precious-metal content against the day’s live spot price. Content, not gross weight: a US 90% silver quarter carries about 0.18 troy ounces of silver, and an American Gold Eagle holds a full ounce of gold in a coin that weighs more than an ounce because it is alloyed for hardness.

3. Collector premium on top. Where a date, a mint mark, a grade or a holder makes a coin worth more than its metal, that premium is added and shown separately. Melt is the floor for us, not the answer.

You see the breakdown in writing before you decide anything. Accept, and you are paid the same day by bank transfer. Decline, and everything comes back to you free and fully insured — nothing is melted or altered before you accept in writing.

Before you box it up

Two things to know before a single coin leaves your house.

Never clean a coin

  • Cleaning is the most expensive mistake in coins. Polish, dips and even a soft cloth leave hairlines that any experienced eye — and any grading service — spots immediately.
  • A cleaned collector coin is worth a fraction of the same coin left alone, and the damage cannot be undone. Toning and patina are not dirt; on many coins they add value.
  • Leave graded coins sealed in their holders. Cracking a coin out of a PCGS or NGC slab destroys the guarantee that made it worth more.

Send coins exactly as they are, in whatever tubes, flips or albums they live in now.

What is not worth mailing

  • Copies and replicas. Reproductions are required to be marked COPY. They carry no metal value and no collector value.
  • Clad and plated “collector” issues. Gold-plated state quarters, layered commemoratives and tribute coins sold on television hold a trace of metal at most.
  • Circulating foreign currency. Modern base-metal coins from abroad have exchange value, not metal value.

Frequently asked questions

How much is my bullion worth?

Bullion coins, bars and rounds are valued on their actual metal content against the day’s live spot price. An American Gold Eagle holds one full troy ounce of gold even though it weighs slightly more, because it is alloyed for hardness — we price the gold, not the gross weight.

Do you buy pre-1965 US silver coins?

Yes. US dimes, quarters and half dollars dated 1964 and earlier are 90% silver, and 1965–1970 half dollars are 40% silver. These are valued on their silver content unless a date or condition makes a coin worth more to a collector.

Should I clean my coins before sending them?

Never. Cleaning is the single most expensive mistake in coins. It leaves hairline scratches that any grader spots instantly and can cut a collectible coin’s value sharply. Send coins exactly as they are, and leave graded coins sealed in their holders.

What is the difference between melt value and collector value?

Melt value is the metal content at spot, and it is the floor. Collector value comes from date, mint mark, rarity and condition, and it can be many times melt. We check every coin for collector value before it is treated as metal — a scarce date should never be sold by weight.

Is my shipment insured?

Yes. You ship on a prepaid FedEx label backed by dedicated jewelry insurance through IFS (In4Sure) that covers full value door to door, both ways, tracked and signature required.

What if I decline the offer?

Everything ships back to you free and fully insured. Nothing is melted or altered before you accept in writing, and the valuation is free whether you sell or not.
