Finally, numbers that know what they are talking about.

Record what you paid and what each copy is worth today. KolleK turns that history into a collection view that answers useful questions without making up the missing bits.

What you paid, kept separate

Cost and value are two different numbers.

Transactions record money that actually changed hands. Valuations record what an object may be worth. Keep both, and the collection stops confusing cost with value. A surprisingly popular mix-up.

A sparse chart is a nudge, not a scolding.

Sparse charts are not a scolding. They are a useful nudge that a few older copies still need a date, a value, or a better story.
