How Coin Collecting Made Me a Better SaaS Founder: Building Products Like a Numismatist

What Coin Collecting Taught Me About Building SaaS Products

Let me tell you a secret: my most valuable lessons in SaaS came not from tech conferences, but from examining rare coins under a magnifying glass. Over years of building products and collecting pennies, I discovered surprising parallels between numismatics and sustainable software development.

Just last month, while authenticating a 1969 D penny, I realized something: the skills that help spot valuable coin errors are the same ones that prevent SaaS founders from chasing shiny distractions. Let me show you how to apply these principles to your product.

The Coin Collector’s Approach to SaaS Development

Finding Your Product’s “Metal Flow”

When I examine coins, I look for metal flow patterns – how the blank metal behaves during striking. In SaaS, this translates to understanding real user behavior versus what we imagine they’ll do.

Here’s how I spot genuine opportunities:

• Pre-strike clues: Actual customer frustrations (not our clever solutions to imaginary problems)
• Natural patterns: How users actually navigate your MVP
• Unexpected dents: Those “this shouldn’t work but does” moments

“Your first 100 users taught me more about product-market fit than any analytics dashboard ever could – if you watch closely enough.”

Building Your Mint: The $300 MVP Stack

Just like the U.S. Mint optimizes production, I’ve refined a cost-effective tech stack through trial and error:


// My bootstrapped architecture
Frontend: Next.js (React)
Backend: Firebase/Firestore
Auth: Clerk.dev
Payments: Stripe + Paddle
Emails: Resend
Analytics: PostHog


This keeps costs below $300/month while handling real traffic. No VC money needed – just like the Denver Mint produced pennies for less than a cent each in 1969.

Your Product Roadmap: Avoiding Feature Scratches

The Right Striking Sequence

Coin dies strike in precise order to create definition. Feature sequencing matters just as much. I learned this the hard way with our analytics tool: we built beautiful dashboards before solving the painful data import process. Turns out users would trade every visualization for reliable CSV exports.

Is That Feature a Scar or a Star?

Use my coin-inspired evaluation matrix:

Anything below 8 impact with high effort? That’s post-mint damage – looks interesting but adds no real value.

Our 13-Week Coin-Strike Launch Cycle

Weeks 1-4: Blank Preparation

• 20+ customer interviews (actual conversations, not surveys)
• Mapping pain points using coffee-stained notebooks
• Building only the riskiest component first

Weeks 5-8: First Strike

We built just enough to test our core assumption. For our document tool:


// Reality-check pseudocode
if (canUploadFile && canComment && trackChanges) {
shipIt();
} else {
whyAreWeStillBuilding();
}


Weeks 9-13: Magnifying Glass Phase

This separates hobbyists from serious builders:

• Watching 100 user session recordings (painful but revealing)
• Finding where users actually get stuck (not where we assumed)
• Mining support tickets for hidden gems

We discovered 78% abandoned during onboarding – not because of features, but because of a three-question survey that felt like an interrogation.

Mint-Worthy Bootstrapping Strategies

The Penny-Pinching Founder’s Guide

If the 1969 Mint could make pennies for 0.8 cents each, your SaaS can optimize:

• Avoid always-on servers like misprinted coins
• Negotiate annual deals – your leverage increases with traction
• Implement metered billing before you need it

By switching to serverless, we cut cloud costs 62% – enough to fund real user testing.

When to Sharpen Your Tools

Coin dies wear down over time. So do marketing messages. When our conversion rates dipped below 1.2%, we knew it was time to recut our messaging “dies.” The result? 3X more qualified leads without increasing ad spend.

Your New Lens for Building Products

Through my coin collecting journey, I’ve learned to:

• Spot genuine opportunities (not surface-level scratches)
• Sequence features like a master coin striker
• Maintain mint-level operational efficiency

That 1969 D penny in my collection reminds me daily: true value comes from substance, not shine. Your users can tell the difference between features that solve real problems and those that just look pretty in the product catalog.

Try this today: Open your roadmap and find one “feature scratch” – something that looks important but lacks user evidence. Replace it with an item that addresses actual customer pain. You’ll feel the difference in your product’s metal flow immediately.
