Introducing Precious Metals Inventory Tool 2.0

I’m excited to share a little project I’ve been working on during my weekends and evenings. It’s a passion project born from my own frustration with tracking my modest silver and gold collection.

Meet Precious Metals Inventory Tool 2.0, a free, client-side web application that helps you track your physical precious metals inventory with ease.

Why I Built This?

Like many of you, I started collecting physical silver and gold as a hedge against economic uncertainty. But as my collection grew, I found myself struggling with:

Tracking purchase prices across different dealers
Calculating my average cost per ounce
Monitoring how my holdings compare to current spot prices
Figuring out my total premium paid (that extra cost above spot)
Simply remembering where I bought each item!

Spreadsheets worked for a while, but they became clunky. Commercial solutions either cost money or felt like overkill for a personal collection. So, being technically inclined, I decided to build my own solution, strictly as a fun learning project.

What It Actually Does (No Fluff)

This is 100% a pet project.

I built it for myself first, and I’m sharing it because I thought others might find it useful too.

Here’s what it offers:

Track your silver and gold holdings with details like type, weight, purchase price, and location
Monitor spot prices (manually entered—no live API for now because, well, pet project!)
Automatic calculations for:
- Current value based on your spot price
- Premium paid per ounce
- Total premium across your portfolio
- Profit/loss calculations
Import/export functionality (CSV, JSON, Excel, PDF, HTML)
Complete privacy—all data stays in your browser (more on this below)
Responsive design that works on mobile but ideal for desktop

Important things to know:

All your data is stored only in your browser’s local storage
Clear your history? Data’s gone. Use private browsing? Won’t save.
No cloud backup, no servers, no nothing—it’s completely client-side
I’m not a financial advisor, and this tool shouldn’t be treated as financial advice
It’s free, always will be, and has no ads (because profit wasn’t the point!)
