Whether you collect coins, banknotes, or stamps, Archimede gives you the tools to catalogue, value, and grow your collection.
Everything a serious collector needs
All the tools to catalogue, organise, and understand your collection — without the spreadsheets.
Add your collection
Each piece gets its own complete record — photos, grades, provenance and all the details that matter to you.
- Category-specific fields for coins, banknotes and stamps
- Photos, condition grades, mint marks and variants
- Purchase cost, current value and insurance all in one record
Organise your way
Create folders and sub-folders named however you like — by country, period, series or theme. Your structure, your rules.
- Freely nested folders, named exactly how you think about your collection
- Group by country, era, series, theme — or any combination you like
Know what you made
Log what you paid and what you sold each piece for. Archimede does the rest — profit per item, total returns, all calculated automatically.
- Log purchase price, date and source for every piece
- Record the sale price when you let something go
- Profit calculated automatically — per item and in total

One dashboard for your entire collection. See the total value, how it breaks down by category, what you've made from sales, and what's still on your wishlist.
- Total value and item count across coins, banknotes and stamps
- Profit summary from all completed sales — updated automatically
