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.

A troy ounce is 31.1035 grams, not the 28.35 grams your kitchen scale calls an ounce. Grams, pennyweight and troy ounces, converted →

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 within 24 hours 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.

Not sure what you have? Photograph both sides — dates and mint marks in focus — and send them to us on WhatsApp before you ship. Sorting it out on a photo costs you nothing.

How it works

01

Request a kit

Tell us what you have. We email a prepaid, fully-insured FedEx label — you pay nothing to ship.

02

Drop it at FedEx

Pack it and drop it off. Insured door to door through IFS (In4Sure), tracked, signature required.

03

We read & value

Every coin is checked for date, mint mark and condition first, then bullion is priced against live spot.

04

Paid within 24 hours

Accept and you are paid within 24 hours by bank transfer — or everything ships back free and insured.

How your coins travel, and how they come back

The same carrier and the same cover in both directions. You never pay to ship, whether you sell or not.

A prepaid FedEx label, by email

Tell us what you have and we email a prepaid, fully insured FedEx label with simple packing instructions. It arrives by email — there is no box to wait for — and it ships on our account, so you pay nothing.

Drop it at any FedEx location

Print the label, pack your coins and hand the package in at any FedEx location. From that moment it is tracked door to door, with a signature required at every handoff. Your package is never left on a doorstep. If you are not sure how to pack it, our step-by-step packing guide walks through it.

Insured to full value, both ways

Cover runs through IFS (In4Sure), a dedicated jewelry insurer — not a carrier’s flat default that stops at a token amount. Your coins are insured for their full value on the way to us and on the way back.

Decline, and it ships back free

Say no to the offer and the exact pieces you sent come back to you, free and fully insured on the same cover. No restocking fee and no fee for our time — and nothing is melted, altered or dismantled before you accept in writing.

The valuation is free whether you sell or not, and shipping costs you nothing in either direction. Slabbed coins travel in their holders and come back in them, unopened.

Coins mixed in with jewelry and silver? Gold, silver and coins in one box — rarity is still read before anything is treated as metal.

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.

What is the fastest way to reach you?

WhatsApp, at +1 786-907-8883. Send a photo of what you have and we will tell you what we can already see, and what we would still need in order to make an offer. If you would rather start in writing, request a free shipping kit from the home page. Either way the valuation is free and there is no obligation.
