Understand your collection statistics
Every collection has a statistics screen that turns your data entry into answers: what is it worth, how has it grown, and where does the value sit. This page explains each figure and, just as important, where each number comes from, so you can trust what you read.
Where the numbers come from
Two rules drive almost everything on this screen. They come from how a copy's history works:
- A copy's current value is its most recent valuation. A copy that has never been valued counts as unvalued, not as zero worth guessing about.
- A copy's acquisition date comes from its earliest acquiring transaction, such as a purchase, trade, gift received, or inheritance. A copy with no such transaction has no acquisition date, so it cannot appear on the time based charts. The screen tells you how many copies are undated so you know what the charts are missing.
If a chart looks emptier than your collection feels, that is the statistics inviting more data entry, not a bug.
The totals
At the top: the item count, the copy count, the total estimated value (the sum of every copy's current value), and the average value per item. You will also see what changed recently: items added this month and value added this month.
Set completion
If the collection has sets with a target count, the screen rolls them up: how many pieces you own against the combined target, and the completion percentage. Only sets with a target above zero take part. A set holding more than its target counts as complete, not over complete.
Value over time
A twelve month chart of your collection's cumulative estimated value, month by month. Each copy joins the line at its acquisition date, at its current value. Everything acquired before the twelve month window is already included in the first point, so the line starts from your real total, not from zero.
Acquisitions per month
How many copies you acquired in each of the last twelve months, driven by the same acquisition dates. A quiet chart here usually means missing acquisition transactions rather than a quiet year.
Breakdowns
- By category. How items spread across your categories. The six largest categories are named, the rest fold into "Other", and uncategorised items are shown as their own slice.
- By condition. How your copies grade, as counts and percentages per condition.
- Value by location. The summed value of copies at each location, so you know what is sitting where. Priya uses this to see how much value lives in her display case versus her safe. Only locations holding value appear.
Top items
The five most valuable items in the collection, ranked by the combined current value of their copies, each shown with the condition and location of its most valuable copy.
