Collection Management Software for Hobbyists with Multiple Collections

One Software for All Your Collections: Guns, Coins, Stamps, Knives & More

Most collection management software forces you to choose: firearms OR coins OR stamps. If you collect multiple types of items, you're stuck managing multiple apps, multiple subscriptions, and multiple databases.

NM Collector takes a different approach: one unified platform for unlimited collection types.

Why Multiple Collections Need Unified Software

The Problem with Specialized Apps:

Gun app for firearms
Separate coin app for numismatics
Another app for stamps
Yet another for knives or antiques
Each requires separate subscription
Each uses different interface
Data trapped in silos
Multiple backup strategies needed

The NM Collector Solution:

One software license covers all collection types
Consistent interface across all collections
Shared skills—learn once, use everywhere
Single backup strategy for all data
Cross-reference between collections
One-time purchase, subscription, and free version options available

Supported Collection Types

Pre-Built Templates:

Firearms Collections: ATF-compliant formatting, FFL tracking, accessories
Numismatic Collections: PCGS/NGC grading, mintage data, varieties
Philatelic Collections: Scott catalog numbers, watermarks, perforations
Knife Collections: Makers, patterns, blade steel, custom vs. production
Japanese Sword Collections (Nihonto): Authentic terminology (mei, hamon, hada, nagasa)
Geological Specimens: Classification, Mohs hardness, localities
Home Inventory: Room-by-room insurance documentation

Custom Collections: Create your own templates for:

Watches
Cameras
Vintage electronics
Art

Any collection you can imagine

Real-World Examples

Note, these are not quotes from real people. These are personas which are fictional, data-backed profile of a typical user, created to help the team empathize with, understand, and design for real people's needs, behaviors, goals, and pain points.

The Retired Military Collector: "I collect military firearms, military knives, and military coins from different eras. Before NM Collector, I was using three different apps. Now everything's in one place with the same interface. I can even note which coins I acquired at the same gun show where I bought a particular rifle."

The Estate Executor: "My father collected guns, coins, stamps, and antique tools. When he passed, I had to inventory everything for insurance and distribution among heirs. NM Collector let me document it all systematically in one place. The offline capability meant I could work on it at his house without internet."

The Multi-Hobbyist: "I'm a firearms instructor who also collects coins and manages home inventory for insurance. One software, one backup strategy, one learning curve. That's efficiency."

Why Offline Matters for Multiple Collections

Privacy Across Hobbies: Nobody needs to know you collect firearms AND rare coins AND valuable stamps. Offline storage means your complete collection profile exists only on your devices.

Simplified Security: One encryption strategy protects everything. Enable OS-level encryption once, secure all your collections.

No Collection Limits: Some cloud apps limit number of items or photos. With offline storage, your only limit is hard drive space.

One Backup for Everything: Encrypted USB backup drive = all collections secured

Pricing That Makes Sense

Cloud Competitors Force You to Pay Per Collection ... for example:

$10/month for gun software
$8/month for coin software
$5/month for stamp software = $276/year for three collections

NM Collector:

One activation = all collection types
Or use free version forever
No ongoing costs
No collection limits
