Why NM Collector is Essential for Philatelists:
Proper Catalog Attribution and Variety Documentation
Track Scott numbers, watermarks, perforations, printing varieties, and all the technical details that distinguish common stamps from rarities. NM Collector understands philatelic terminology and provides fields specifically designed for stamp collectors. Unlike generic database software, you won't need to retrofit spreadsheet columns or create workarounds for essential stamp data.
Mint and Used Condition Tracking
Document gum condition (original, never hinged, hinged, no gum), cancel types, centering, and other condition factors that affect philatelic values. The template includes appropriate fields for both mint and used material, allowing you to properly document collections that include both categories.
​
Complete Privacy for Valuable Philatelic Collections
Rare stamps represent concentrated value—a single item might be worth thousands. Storing collection details on cloud servers creates unnecessary risk. NM Collector eliminates this exposure by keeping all data local. Your Scott numbers, values, and collection inventory remain completely private and under your control.
​
Mobile Access at Bourses and Auctions
Avoid duplicate purchases and make informed decisions with instant offline access to your collection. Check what you own, verify varieties, reference condition of existing items, and add new acquisitions immediately—all on your phone or tablet without internet connectivity. NM Collector travels with you to every show and auction.
​
Multi-Format Philatelic Management
Manage stamps, covers, postal history, first day covers, and other philatelic material in one integrated system. Create separate collections for each category or combine everything with filtering and reporting. Link related items across collections—connect covers to the stamps they contain, or link first day covers to corresponding stamp issues.
​
Investment and Insurance Documentation
Track acquisition costs separately from current values, monitor collection appreciation, and generate professional reports for insurance companies or estate planning. Philatelic collections require proper documentation for insurance coverage—NM Collector provides detailed records with high-resolution photos that insurance companies accept.
​
Worldwide Collection Support
Whether you collect U.S. classics, British Commonwealth, or worldwide stamps, NM Collector supports multiple catalog systems and provides flexibility for any collecting specialty. Create country-specific collections or manage everything together with powerful filtering and search capabilities.
​
No Subscription Required for Basic Collection Management
Try full features free for 30 days, then choose a lifetime activation or use the free version forever. Your philatelic data remains accessible regardless of payment status—no locked features, no loss of data access, no recurring fees unless you choose them.
FAQ Stamp Collecting
Q: Does NM Collector include Scott catalog numbering? A: Yes. The philatelic template includes a dedicated Scott Catalog Number field for documenting U.S. and worldwide stamps. You can also track Michel, Stanley Gibbons, or other catalog systems using the custom fields feature. The template is designed specifically for serious stamp collectors who need proper catalog attribution.
​
Q: Can I track watermarks, perforations, and printing varieties? A: Absolutely. NM Collector's stamp template includes fields for watermark type, perforation measurements, printing method, and variety information. These details are essential for proper identification and value assessment of philatelic material. You can also document paper type, gum condition, and other technical attributes that affect grade and value.
​
Q: How does NM Collector handle mint vs. used stamps? A: The stamp template includes a Condition field where you can specify mint (with original gum, never hinged, hinged, disturbed gum) or used (including cancel type and date if relevant). This is critical information for philatelic collections where mint vs. used can mean dramatic value differences.
​
Q: Can I manage covers, postal history, and stamps in the same software? A: Yes. You can create separate collections for stamps, covers, postal history items, and first day covers all within NM Collector. The Related Items feature lets you link covers to the stamps they contain, or connect postal history items to related stamp issues. This is perfect for comprehensive philatelic collections that span multiple categories.
Q: Is my stamp collection data private and secure? A: Yes. NM Collector stores everything locally on your devices with zero cloud storage. Your catalog numbers, values, and collection inventory never touch external servers. This is particularly important for high-value philatelic collections where theft risk increases if collection details are exposed through online databases.
​
Q: Can I use NM Collector at stamp shows and bourses? A: Definitely. NM Collector works completely offline on iOS and Android devices. Take your phone or tablet to shows, check what you already own, verify Scott numbers before purchasing, identify duplicates instantly, and add new acquisitions on the spot—all without internet access. Your complete collection is always available when you need it.
​
Q: How do I document plate blocks, coil pairs, and other multiples? A: The stamp template can document individual stamps, multiples (blocks, strips, pairs), plate blocks, booklet panes, souvenir sheets, or any other philatelic format. Use the Item Name and Description fields to specify what you're documenting, and the Quantity field to track multiples of the same item.
​
Q: Can NM Collector handle worldwide stamp collections? A: Yes. The Nationality field lets you organize stamps by country, and you can use multiple catalog systems (Scott, Michel, Stanley Gibbons) simultaneously. Whether you collect U.S. only, British Commonwealth, or worldwide, NM Collector provides the flexibility you need. Create separate collections by country or combine everything in one comprehensive collection with country-based filtering.
