5 Critical Mistakes to Avoid When Grading Rare Coins (And How to Recover from Them)
September 21, 2025My 6-Month Journey Navigating PCGS Grading Inconsistencies: A Real-World Case Study on a Rare 1922 Peace Dollar
September 21, 2025Ready to move past the basics? These advanced PCGS grading techniques will help you spot hidden value like a seasoned pro.
Mastering the Art of Resubmission
Inconsistent grading happens more often than you’d expect—especially with rare coins like the 1922 Peace Dollar. I’ve been there myself. Knowing when and how to resubmit a coin is half the battle.
One of my go-to strategies? Targeting specific graders or using third-party validations like CAC to push for a higher grade.
When to Crack and Resubmit
Timing and condition matter most. If your coin gets a details grade but you believe it deserves a straight grade, try this:
- Check market trends—is the coin undervalued at its current grade?
- Inspect surfaces carefully. Sometimes, old residue or lacquer can be removed by a professional.
- Talk to experts you trust, or submit through dealers experienced with rare types.
Take that 1922 Peace Dollar: it went from “PR, Unc details altered surfaces” to a straight PR63 with CAC approval. That wasn’t luck—it was smart strategy.
Optimizing Your Submission Strategy
Blind submissions are for beginners. Pros fine-tune every detail to maximize returns.
Use Pop Report Data
PCGS population reports are packed with insights. For example, only eight 1922 Peace Dollars in PR67 have been graded. That makes each one incredibly rare.
Compare pop data with auction results to spot undervalued coins.
Try this: Use PCGS CoinFacts to follow grading trends. You’ll notice how labels shift over time—like 1907 High Reliefs now designated “SP.”
Target the Right Graders
Not all graders specialize in rare coins. For matte proofs or early issues, find graders with relevant expertise. Building a relationship with submission desk managers can help, too.
Professional Tips for Maximizing Value
There’s more to advanced grading than resubmission. Here’s how to boost appeal and market value.
Understanding CAC’s Role
A CAC sticker isn’t just a badge—it’s a trusted signal of quality. Coins approved by CAC often sell for more because they’ve been vetted by industry experts.
In the case of the Peace Dollar, the sticker added credibility to the PR63 grade.
Here’s an example: I once submitted a 1796 Draped Bust dime. It graded MS67 at first, but after resubmission with proper context, it earned an SP67 designation.
Navigating Auction Dynamics
Auction prices can swing widely when grades are in question. That Peace Dollar sold for $144K with a details grade, but only $190K with a straight grade—a smaller jump than expected.
My advice: If you disagree with a grade, consider pulling the coin and resubmitting before auction. Major houses like Heritage often allow this for high-value lots.

Tech and insider knowledge can give you an edge in PCGS coin grading.
Code Snippets for Market Analysis
For collectors who love data, here’s a simple Python script to scrape PCGS pop reports and spot grading inconsistencies:
import requests
from bs4 import BeautifulSoup
# Example URL for PCGS pop report data
url = 'https://www.pcgs.com/pop'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
# Parse data to find coins with low populations but high value potential
# Focus on coins with recent grade changes or designations
This automates trend-spotting, like the rise in “SP” labels for certain coins.
Learn from Historical Precedents
Past cases—like the 1794 Flowing Hair dollar redesignated as “Specimen”—show how rare coins are often misgraded at first because they’re unique.
As one veteran collector put it, “Grading is subjective. That’s why CAC stickers carry so much weight.”
Elevate Your Numismatic Game
Advanced grading blends strategy, knowledge, and persistence. Master resubmission, use pop reports, target the right graders, and read auction trends to uncover hidden value.
Remember: grading inconsistencies aren’t setbacks—they’re opportunities. Use these pro techniques to transform your collection.
