A price-guide value is an editorial estimate, not a transaction. Guides lag the market and smooth over grade and condition. It is useful as a floor for how the trade thought about the object, and it should be checked against a realized sale before anything rests on it.
By reference price, Australia 1932 5/- Sydney Harbour Bridge is number 89 of 99 in the stamps entries of the FLOAT 100. 75 of those 99 rest on a realized sale; the rest carry an asking price or a guide value, and each page says which. Rank within the FLOAT 100 itself (87 here) is editorial: how much an object defines its field, not price alone.
How this is made
- The figure
- One reference price, 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.
