Estimate before you submit
Where would your piece land?
Choose the category, then hold your item beside each published criterion and record what you see. The estimator weights your answers exactly as the standard does and returns the band an examiner would most likely assign — so you know what you are sending before you ship it.
Step one — the category
01
Select
Pick the category your piece belongs to — each is graded on its own scale.
02
Compare
Work through the criteria with the item in hand, at the magnification we use.
03
Submit
See the likely band, then send it in for a certificate that states the reasoning.
An estimate is not a grade
The number on a certificate comes from the piece in hand, never from a description.
Use the estimator to decide whether grading is worth the fee and to spot the defect that will limit the result. The examiner's finding, recorded with imaging and the criteria cited, is the only grade that is binding.
