My Final Four Coin Collecting Adventures
July 1, 2025My Quest to Build a Coin Sorting Machine by Date and Mint
July 1, 2025You never know where a coin might turn up, do you? My ordinary trip to the laundromat last week became something special when I spotted a 2015 S Blue Ridge Parkway quarter in the change machine’s output. That little surprise got me thinking differently about modern U.S. coins, and I’d like to share what I learned with you.
Was It Proof or Business Strike? Solving the Mystery
Honestly, this quarter had me stumped at first. That ‘S’ mint mark usually screams proof coin, but where was the mirror finish? The frosty luster I expected just wasn’t there. After turning it over in my hands a few times, I realized it was probably a business strike. Here’s what tipped me off:
- Surface tells the story: Proofs keep their deep mirrors even with light wear, but this had a more everyday matte finish.
- The S mark isn’t always proof: Since 2012, San Francisco made both proofs and regular clad quarters with the S mint mark. These business strikes aren’t meant for circulation but sometimes escape into the wild.
- Condition clues: Even well-preserved proofs hold their distinctive shine, which mine lacked. The copper edge confirmed it was clad rather than silver.
Why S-Minted Quarters Make Great Finds
Here’s what surprised me: S-minted business strikes like this Blue Ridge Parkway quarter are actually scarce in circulation. Only about a million were made for each design in the series—fewer than the W quarters but without the same collector frenzy. They occasionally slip out when folks like us (I’ll admit, I’ve spent extra coins from Mint rolls!) spend them. While you won’t get rich (maybe $1-2 for uncirculated examples), they’re perfect for albums or as conversation starters at club meetings.
My Field-Tested Tips for Coin Hunting
Laundromats and car washes have become my secret hunting grounds. I swap about $100 for quarters every month or two, and it’s paid off more than once. Try these approaches:
- Cleanliness counts: Always wash up after handling machine coins—they can get grimy! I make a beeline for the sink after collecting my haul.
- Target high-volume spots: Machines at laundromats or car washes process tons of coins, increasing your odds of finding something special.
- Hunt respectfully: I never dig through return slots—it feels awkward. I stick to clean exchanges through the machine.
Grading and Collecting Modern Finds
Condition makes all the difference with modern coins like this. Even worn examples can be keepers if they’re well-preserved. Look for sharp details and minimal contact marks—business strikes in AU or better condition really stand out. While S-minted quarters don’t get the attention of Ws right now, I think they’re overlooked gems. National park designs like this one often resonate with collectors years later.
This little quarter reminded me that coin collecting isn’t just about precious metals—it’s about the stories and little surprises that pop up in the most ordinary moments. So next time you’re doing laundry or getting change, take a second to look at those coins. Who knows? You might find a hidden treasure of your own!
