Predicting the Future Value of Your Coin
How to Predict the Future
Predicting future value isn’t about luck, it’s about signals.
Coins that tend to stand out over time usually start with strong fundamentals: limited mintages, low survival rates, and something distinctive about the issue.
For example, a coin like the Morgan Dollar might be common in general, but certain dates or mint marks can quietly be far scarcer than they appear.
What's Considered Low Mintage?
While coins like the Morgan Dollar often had mintages in the millions, under 1 million is considered low (and under 100,000 scarce), making them naturally more appealing as availability shrinks.
Famous Examples
The 1995-W Proof American Silver Eagle
With only 30,125 coins ever made, this is the lowest-mintage and most sought-after "key date" in the entire Proof Silver Eagle series.
Due to its rarity, these coins, particularly in perfect NGC PR70 DCAM/Ultra Cameo condition, can command prices often exceeding $4,000 to over $10,000.
The 1893-S Morgan Silver Dollar
Dubbed the "King of Morgan Dollars," this coin is exceptional due to its low 100,000 mintage and poor survival rate.
Circulated examples generally start at over $3,000, while high-grade, uncertified examples can exceed $1,000,000.
How Much Does Condition Matter?
Condition is critical when it comes to a coin’s value. Small differences in grade can translate into big differences in price.

The Difference?
Almost $20,000
These are 1928-P Peace Dollars
This coin is already scarce because it was one of the last of the original series. An NGC MS65 (Mint State 65) might sell for around $2,000–$4,000, but a jump to NGC MS66 can push the value to roughly $13,000–$28,000.
That’s more than triple the price for a single point of grading difference, showing just how much condition drives collector demand.
The Scale
Coins are graded on a scale from 1 to 70 from grading services like NGC, with higher numbers indicating sharper detail, fewer marks, and overall better preservation. Collectors and investors pay premiums for coins in higher grades because they’re rarer and more visually appealing.
The Exception: Minting Mistakes
Minting mistakes can actually make a coin more valuable because they create something rare and unexpected. Errors like double strikes, off-center prints, or missing elements are often caught early, so only a small number make it into circulation.
A famous example is the 1955 Doubled Die Lincoln Cent, where the date and lettering appear clearly doubled due to a misalignment during minting. While it was originally just a one-cent coin, well-preserved versions can sell for thousands today because of their rarity and visual uniqueness.
Bringing It All Together
At Kavanaugh’s Coins, we focus on modern rarities that not only look great today but also have strong potential to grow in value over time. Our collection features pristine (NGC PF 70) and near-perfect (NGC PF 69) coins, all struck in .999 fine silver and in low-mintage of fewer than one million.
These factors come together to create all the right ingredients for lasting value, so you can feel confident that the coin you’re adding to your collection has real potential and collector appeal.
