Why Legacy Code Maintenance is the Penny Problem of M&A Technical Due Diligence
December 2, 2025The Hidden Signal in Startup Valuation: Why Technical Rigor Outshines Price Guides for VCs
December 2, 2025
New to collecting coins? Let’s walk through what really matters in valuing your finds.
When I first started collecting, I treated price guides like holy scripture. Big mistake. After years of buying, selling, and sometimes overpaying, I’ve learned these guides are more like training wheels – helpful at first, but limiting if you never take them off.
Here’s the truth no one told me: that little number in the book? It’s just someone’s educated guess. Let me show you how to develop your own valuation skills.
How Coin Price Guides Really Work
The Promise vs. The Reality
Price guides seem straightforward. They list values based on:
- Grading scales (like MS-60 to MS-70)
- How many exist (population reports)
- Past auction results
- Current market trends
But here’s what I’ve learned from handling thousands of coins:
- They’re always playing catch-up: Most update quarterly while markets change daily
- They miss hidden gems: Only certain sales get counted
- No two coins are twins: Same grade ≠ same value
Your Hands-On Valuation Starter Kit
4 Steps I Wish I Knew Earlier
Instead of just checking one guide, try this:
- Check multiple sources: Compare PCGS, NGC, and CAC values side-by-side
- Look at actual sales: Search Heritage Auctions and GreatCollections archives
- Expect the dealer markup: Retail prices often run 20-30% above book
- Eye appeal matters: A beautiful coin can add 50% to guide prices
Real Example: The 1827 Dime Shock
Check out these wild differences for the exact same coin grade:
- PCGS Guide: $32,500
- CACG Guide: $19,500
- Last Auction: $28,200 (back in 2014!)
See why trusting one source is risky? When I met collectors holding these dimes, all valued theirs over $40,000 – way above any guide.
Myths That Trick New Collectors
Myth: Higher Grade = Higher Value
I once bought an MS-65 Morgan dollar for $200. Later sold an “MS-64” version for $275. Why? The lower-grade coin had stunning rainbow toning. Remember this:
“The number tells part of the story, but beauty opens wallets.”
Myth: Guides Match Today’s Prices
During the 2021 silver rush, check what happened:
| Guide Said | What Dealers Paid | What They Sold For |
|---|---|---|
| 18x face value | 22x face value | 25x face value |
Guides were months behind actual trading.
When Price Guides Cost You Money
The Collector’s Trap
Last year, a fellow collector passed on a $4,500 coin priced at $6,000 because his guide said $4,250. That coin later sold for $7,200. Price guides can cause:
- Missing great deals
- Overpaying for “book price” coins
- False confidence in valuations
What Dealers Know That You Don’t
Smart sellers watch factors guides ignore:
What Really Adds Value:
1. Attractive toning
2. Sharp striking
3. Clean surfaces
4. Collector demand
5. Rarity competitions
Practical Tips for Smarter Valuing
Build Your Own Price Tracker
My simple method beats relying on guides:
- Track your favorite coin series
- Record auction results by grade
- Note dealer asking prices
- Watch population reports
Spending 30 minutes weekly saved me thousands.
The 3-2-1 Safety Check
Before any big purchase ($500+), I always get:
- Three recent sales records
- Two dealer quotes
- One extra grading opinion
Growing Your Valuation Skills
Price guides are tools, not answers. Through trial and error, I’ve discovered:
- Always check multiple guides
- Follow auction results like a hawk
- Understand dealer pricing
- Special coins break all the rules
The real secret? Nothing beats holding coins in your hand. Start small, keep notes, and watch your valuation skills grow. Remember – a coin’s true worth is what a knowledgeable buyer will pay, not what any book declares.
