ModernCoinMart’s Scarce & Unique Coin Division offers our customers an exclusive opportunity to purchase coins that are only sometimes available on our website due to high demand and/or limited availability. Browse our current selection above. Inventory changes frequently, and once these coins are gone, they may not return.
What Is the MCM Scarce & Unique Division?
The Scarce & Unique division is ModernCoinMart’s curated marketplace for rare, hard-to-find, and one-of-a-kind coins that fall outside our standard inventory. These are coins that are only sometimes available on our website due to high demand and limited availability, from key date classics and low-population certified rarities to unique error coins, historically significant pieces, and individually sourced collector treasures. Each item in this division represents an exceptional find, carefully vetted by MCM’s numismatic team before being made available to our customers.
What Types of Coins Are Found Here?
The Scarce & Unique inventory is ever-changing, but may include:
- Key date and semi-key date coins — highly sought-after dates within popular series
- Low-mintage certified coins — PCGS and NGC graded examples with small population reports
- Error coins — off-center strikes, doubled dies, and other minting anomalies
- Historic U.S. type coins — early American coinage, obsolete denominations, and pre-1933 gold
- World coins and rarities — scarce international issues with strong collector demand
- Unique and individually sourced pieces — coins that don’t fit neatly into any standard category
Because inventory is sourced on an individual basis, no two listings are alike, and availability can change at any time.

Tips for Collecting Scarce & Unique Coins
Building a collection of rare coins is a rewarding but nuanced pursuit. A few best practices:
- Act quickly — scarce inventory sells fast and is rarely restocked
- Prioritize certified coins — third-party grading from PCGS or NGC protects your investment
- Research population reports — coins with low populations at a given grade carry added scarcity value
- Focus on a series or theme — targeted collecting often yields the strongest long-term results
- Buy the coin, not just the holder — condition, eye appeal, and strike quality all matter

Frequently Asked Questions About Scarce & Unique Coins
What makes a coin “scarce” or “unique”?
A scarce coin is one with a limited surviving population, low original mintage, or strong collector demand that consistently outpaces supply. A unique coin is one with no known duplicate, whether due to an unusual error, a one-of-a-kind provenance, or a singular minting circumstance. Both categories are valued above comparable common-date coins.
Are coins in the Scarce & Unique division certified?
Most coins offered through MCM’s Scarce & Unique division are certified by PCGS or NGC, providing independent authentication and grading. Occasionally, raw (uncertified) coins of exceptional quality or historical significance may also be offered; these are always clearly identified.
How often does inventory change?
Scarce & Unique inventory is sourced on an individual basis and can change at any time. High-demand pieces often sell quickly. We recommend checking back regularly or contacting our team directly if you are looking for a specific coin.
Can I request a specific scarce or unique coin?
Yes. MCM’s Scarce & Unique division welcomes inquiries from collectors looking for specific coins, key dates, or rare pieces not currently listed. Contact our team, and we will do our best to source what you’re looking for.
How are prices determined for scarce and unique coins?
Pricing is based on current market data, recent auction results, population report data from PCGS and NGC, and the individual characteristics of each coin. MCM strives to offer fair, market-informed pricing across all Scarce & Unique listings
