What “Appraisal” Means at NOSTOS

At NOSTOS, an appraisal is an item-by-item grading and valuation:

Value Factor	Collector Assessment Standard	NOSTOS Processing Protocol
Condition Grading	Loose, CIB, or factory sealed tier	Exact structural grading of label, box, and disc
Authentication	Visual and internal board logic	3.8mm Gamebit teardown and regional verification
Market Data	Subjective eBay “Buy It Now” listings	90-day rolling market averages

1. Condition grading - each item is graded: loose, CIB (complete in box), sealed. Condition within each tier (label quality, box integrity, disc surface) is noted.

2. Authentication - cartridges suspected of being reproductions or counterfeits are inspected. This protects you from unknowingly accepting trade-in credit for fakes, and protects NOSTOS from buying them.

3. Market data lookup - values are benchmarked against 90-day rolling market averages for the specific condition grade. Japanese imports are valued against Japanese market data.

4. Trade-in offer - a cash or store-credit offer is made. You’re under no obligation to accept. You’ll see the data behind the numbers.

What Affects an Appraisal Value

Not every copy of the same game is worth the same amount. The delta between a rough loose cartridge and a tight CIB copy of the same title can be three times or more on sought-after games. Here is how the major variables break down.

Condition Tiers

Tier	What It Means	Typical Value vs. Loose Baseline
Loose, untested	Cart or disc only, not powered on	Baseline
Loose, tested working	Confirmed boots and saves correctly	1.1x to 1.2x
Loose, excellent label	No writing, tears, or fading; sharp corners	1.2x to 1.4x
CIB, missing one component	Box present but manual or tray absent	1.5x to 2x
CIB, complete	Cart, box, manual, and all inserts present	2x to 3.5x
Sealed	Factory or re-seal, verified original	4x to 10x or more depending on title

The tested-vs-untested distinction matters most on hardware and battery-backed cartridges. A cartridge that no longer saves is a different item from a fully functional one, and the offer should reflect that. During appraisal, every battery-backed cart is tested: the save is written, the unit is powered down, and the save is confirmed to persist on power-up. That 15-minute step can meaningfully change what an item is worth.

Board Condition

For cartridges, what is inside the shell matters as much as what the label looks like. Corrosion on the PCB edge connector, lifted traces from aggressive cleaning, or evidence of a prior battery swap done with acid-core solder are all noted. A pristine label on a corroded board is still a corroded board. A worn label on a board with a clean edge connector is a working game that will outlast the cosmetic damage. Both of those facts affect the offer.

Completeness Premium

“Complete in box” is not a binary. An SNES game with the cartridge, box, manual, and tray insert commands a meaningfully different price than the same game with the box only. For titles where the insert, warranty card, or registration slip is itself collectible - certain Nintendo first-party titles, Black Label PlayStation RPGs - missing those components is a real reduction in value. Knowing what a complete copy looks like for a given title is part of what NOSTOS brings to an appraisal.

Market Timing

Retro game pricing is not static. Platform anniversaries, major speedrun events, and JRPG re-releases on modern hardware routinely cause 20 to 40 percent spikes on specific titles for 60 to 90 days. The reverse also happens: a game that received a Switch port or an Xbox Game Pass inclusion will often soften in the loose cartridge market within a few months of that release. Appraisals at NOSTOS use 90-day rolling averages to smooth out short-term noise while capturing genuine trend shifts.

Platform-Specific Demand Cycles

Some platforms have structural demand patterns worth understanding. Saturn collecting has been in a multi-year appreciation cycle driven by a small but active enthusiast base and genuinely limited production runs on certain titles. Game Boy Color and GBA have seen sustained demand from the handheld collector segment. PS1 long-box games carry extreme condition sensitivity: a well-worn long box is dramatically less valuable than a near-mint one because the boxes crush at corners during even light handling. Knowing the platform context is part of giving an accurate appraisal rather than a generic number.

From the Bench

Every collection that comes through the shop starts with the same triage process. The lot goes on the table. Hardware gets separated from software. Anything that looks like it has spent time in a garage or attic gets a closer look before it goes anywhere near a test rig, because connectors that have been sitting in humidity corrode, and pushing a corroded cartridge into a console risks damage to both.

From there, hardware gets powered on. A console that boots to the BIOS screen is not the same as one that runs a title for 30 minutes without video dropout or spontaneous reset. For disc-based systems, the laser gets tested with a pressed game that is known-good before anything unfamiliar goes in. For cartridge systems, the edge connector pins get inspected under a loupe. A 72-pin connector on a front-loader NES that has never been replaced will pull cartridges with more resistance than a fresh connector, and that shows up in testing: intermittent video, slow boots, games that need a specific insertion angle to make contact.

Software gets sorted by platform and graded individually. Label condition, board condition on cartridges, disc surface on optical media, and completeness. For anything that crosses a price threshold, current sold listings get pulled and filtered by condition tier before a number gets committed. By the end, a seller has an itemized breakdown, not a lump-sum offer. If a particular title is carrying most of the collection’s value, that is visible in the sheet. There are no hidden cross-subsidies where a valuable game props up a low offer on everything else. The goal is to hand you a number you can verify, not one you have to take on faith.
