"When you collect limited-edition resin and diecast from CMC, BBR, Spark, and AutoArt, documenting serial numbers, edition sizes, and certificate numbers is critical for insurance. My SageDoer assistant cataloged my entire 1,400-piece collection into Sortly with high-res photos, box condition notes, and valuation receipts."
Gordon Albright
Private Collector, Scuderia Scale Vault
"Differentiating between original 1968 US casting vs. Hong Kong base variations, Spectraflame paint shades, and wheel types requires forensic eyes. SageDoer researched casting codes, tracked auction realized prices across eBay and Heritage, and updated our sales inventory at $6/hr with zero errors."
Kendra Lindqvist
Owner, Vintage Diecast Exchange
"Liquidating a massive 30-year HO and O-scale brass train estate was overwhelming. Our assistant cataloged every locomotive by builder, importer, road name, DCC sound decoders, and wheel arrangement. They formatted complete auction lot manifests that fetched 30% above estimated reserves."
Derek Townsend
Estate Executor & Appraiser, Keystone Heritage Assets
"We source rare vintage Tamiya kits, Kyosho Mini-Z models, and P-Bandai releases from Yahoo! Japan Auctions and Mandarake via proxy services (ZenMarket, Buyee). Having our SageDoer assistant monitor closing bids, translate listing descriptions, and log tracking saved our business 20 hours a week."

Engineered to Solve the 6 Biggest Model Collection Bottlenecks
Passionate hobbyists, model dealers, and estate curators shouldn't spend their weekends entering part numbers into spreadsheets, deciphering Japanese auction listings, or cross-referencing variant codes.
Single Dedicated Model Collection Lead
Never manage disjointed data entry freelancers or explain casting scales from scratch. You communicate strictly with your assigned Project Manager who enforces your cataloging schema, grading standards, and photo naming conventions.
Pay Purely for Output, Never Supervision
We exclusively bill for the verified hours spent auditing models, logging provenance, updating databases, and tracking auction bids. Your dedicated Project Manager's quality checks, audit verifications, and valuation proofing are 100% complimentary.
Precision Provenance & Valuation Archiving
Insurance underwriters and auction houses demand verifiable paper trails. We catalog Certificates of Authenticity (COA), limited edition numbers (e.g., #042/500), original manufacturer receipts, and condition grading (MIB, BNIB, Mint Loose).
Global Auction Sourcing & Proxy Bidding
Never miss holy-grail castings listed overseas. We monitor Yahoo! Japan Auctions, Mercari Japan, Buyee, ZenMarket, eBay International, and European auction portals (Catawiki), tracking closing bids within your set budgets.
Strict Collection Privacy & Security NDAs
High-value collectibles demand discretion. Your storage locations, home vault addresses, exact collection valuations, and transaction histories are protected under legally binding non-disclosure agreements with password-vaulted access.
Zero Ghosting During Estate Acquisitions
When you acquire a 2,000-piece estate collection or prepare an inventory catalog for upcoming auction consignment, our internal bench scales up instantly using documented SOPs. Your cataloging deadlines are never missed.
Factually Proficient in the Platforms Model Curators Rely On
Our virtual assistants possess hands-on operational proficiency in the exact inventory software, collector databases, auction marketplaces, and valuation engines used across modern scale modeling.
Real Tasks Delegated by Collectors & Curators Daily
From logging manufacturer part numbers and documenting condition grades to tracking proxy bids in Tokyo and generating insurance valuation schedules, here is what your managed assistant handles.
Manufacturer Reference & SKU Data Entry
Cataloging exact casting specifications: brand (AutoArt, Minichamps, Spark, BBR, Tamiya, CMC), manufacturer part number, vehicle model year, race livery, driver name, and scale ratio (1:18, 1:43, 1:64, 1:72).
Standardized Condition Grading Documentation
Recording rigorous condition assessments across model bodywork and original packaging: Mint-In-Box (MIB), Brand New In Box (BNIB), Mint Loose, paint rash/crazing, decal silvering, broken antennas, or box shelf wear.
COA & Limited Edition Serial Archiving
Extracting and cataloging limited production run certificates of authenticity (e.g., #034 of 250 pieces), signed plaques by racing drivers or designers, and linking digital scans to item records.
Macro Photography Organization & Defect Tagging
Organizing high-resolution macro photography (front 3/4, rear, undercarriage, interior cockpit, box flaps, factory seals) into standardized cloud folder hierarchies with item SKU watermarking.
