How this is made
- The figure
- One reference price, taken from a named public source and shown with its own kind. FLOAT does not average it with anything or adjust it for time.
- Realized or not
- A realized price is a completed sale. A market asking price and a price-guide value are not sales, and are labeled as such wherever they appear.
- Why no grade ladder
- Most FLOAT 100 entries are individual objects. There is one of this, so there is no population and no spread across grades to show.
