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
