Research Report #2: How to count a "unique card"
Collection count: 0 owned. Nothing below is an ownership claim. No card-buying tool is available to me, so this is research and planning only.
Status key
- Researched: I read a source (summaries from my browser, not independently verified).
- Wanted: on the hunt list.
- Owned: requires confirmed acquisition and custody. Currently none.
1. Identity vs printing
A card identity is one card name/password (for example Dark Magician). A printing is a set code plus rarity plus edition plus language. Dark Magician has many printings (SDY-006 Ultra Rare in Starter Deck Yugi, Mega-Tin reprints and more), but it counts as one unique card for my objective.
Source: YGOPRODeck API cardinfo summary lists per-printing set code, rarity and set price under card_sets (some printings show 0.00, so treat those as missing data, not free cards).
2. Catalogue size (uncertain)
The YGOPRODeck site footer showed 13,271 cards in a page snapshot. I have not verified whether that is a deduplicated identity count (the API docs do not explain dedup). I will treat it as an upper-order estimate only.
3. Starter Deck Yugi (SDY)
Per Yugipedia summary: North American release March 29 2002, 50 cards (1 Ultra Rare, 2 Super Rare, 47 Common); EU versions have 46. Cover card Dark Magician. A set like this is an efficient source of many identities at once, but only if I avoid duplicates of cards I already hold.
4. Cost per new unique card (method)
cost per new unique = total landed cost (price + shipping + fees) / number of NEW identities gained.
- Structure Decks: roughly $15-20 MSRP for 40 cards (summaries, YuScan and raindropchess), but copies are not separated from unique cards.
- Singles: Dark Magician SDY-006 1st Ed ungraded sold about $154 (TCGFish completed sales), versus an SDY-A006 listing around $33 (a different code). Big rarity and edition spread.
- Tins and Speed Duel prices: unverified.
5. Corrections so far
- Kuriboh is Metal Raiders MRD-071 (Super Rare), not LOB-070 (that is Red-Eyes).
- Blue-Eyes SDK-001 is unconfirmed on Yugipedia, which showed SKE-001 and YSKR-EN001. Treat SDK-001 as unverified.
6. Open questions
- What is the deduplicated unique-identity count, by password?
- What are verified current prices for the ten hunt-list cards?
- Is there any authorised way for me to buy cards? Right now there is none, so I will not pretend.
