The Collector's Handbook
Learn every tracker in four steps and get the honest breakdown of how your values and collection scores are calculated.
BrickVault
Your LEGO collection, cataloged in seconds per set.
What makes it different
- Type the set number from any box and the name, official photo, year, theme, and piece count fill in automatically.
- Every minifigure in the set comes along too, with its own picture.
- Track what you paid against what each set is worth today.
- Stats row totals your sets, pieces, minifigs, and collection value.
Quick start
- 1Find the set number printed on any LEGO box (for example 75192).
- 2Type it in and hit Look up set. Everything fills in automatically.
- 3Add what you paid and what it is worth today, then Add to my vault.
- 4Watch your stats row grow as you add more sets.
Dugout
Baseball cards tracked like a real binder, valued like a portfolio.
What makes it different
- Find cards pulls up real photos of the exact card you are adding, in every version, so you can pick yours.
- Prices come from live listings, and you can always set the true sold-comp price, which then wins everywhere.
- Grades and graders (PSA, BGS, SGC, CGC) show as badges right on the card.
- The binder view lays out every card at true 5 by 7 proportions with gain and loss vs what you paid.
Quick start
- 1Hit Add a card and type the player, year, and brand.
- 2Hit Find cards. Real photos of that exact card pop up. Click yours.
- 3The photo and a market price fill in. Check sold comps and set the real price for accuracy.
- 4Save it and watch your portfolio stats update.
Holodex
TCG cards with real scans and live market prices.
What makes it different
- Type any card name and real scans pop up: every printing, every rarity.
- One click adds the card to your vault with its live TCGplayer market price attached.
- Partial names work, so typing Chariz still finds Charizard.
- Collection value updates as market prices move.
Quick start
- 1Type a card name, like Charizard, and hit Find cards.
- 2Real card scans pop up. Click the one you own.
- 3It lands in your vault instantly with its live market price.
- 4Add your whole binder this way, a few seconds per card.
How collection scores are calculated
Your collector score is one honest formula: total collection value divided by your personal goal, times 100.
Example: your goal is $1,000 and your collection is worth $420. Your score is 42, which lands you in the middle ranks. Reach $1,000 and you hit 100, the top rank. The ladder climbs through rookie tiers under 10, collector tiers through the middle, and elite tiers past 70, so every single card or set you add moves the needle.
The score compares you to your own goal, never to other collectors. Set the goal that fits your hobby: $250 for a starter shelf, $10,000 for a serious vault. You can change it any time and your score recalculates instantly.
How values are determined
Holodex attaches the live TCGplayer market rate at the moment you add each card, pulled from the card database that also supplies the scans.
Dugout suggests a price from the live listings behind the card photo you pick. For accuracy, check real sold comps on eBay and enter the true price. Your number always wins over the suggestion, and the card is badged so you know which is which.
BrickVault verifies the facts (name, year, pieces, minifigs) against the Rebrickable database, and uses the value you enter for pricing. Check sold listings for retired sets, they are often worth far more than retail.
Every number on Interlock is an estimate for tracking purposes. Always confirm against real sold listings before buying or selling. Nothing here is financial advice.
Your data, protected
Your collection saves to your account the moment you add anything. Close the tab, switch devices, sign back in, and it is all there. Every record is locked to your login with database-level security, so no other user can ever see your collection. We never sell or share your data. It exists for one purpose: showing you your own collection.
