Items
For each sale there are a number of elements, divided into three categories:
Capability e.g. ROM version, Memory size
Functionality e.g. Working unit, failed disk drive
Quality e.g. Case condition, box/poly condition
Capability and functionality are objective whereas quality is clearly subjective based on peer review within the community.
Quality Grading
Subjective valuations use a grading scale similar to other second hand items such as comics and other collectables.
Grading | Percentage |
---|---|
Mint | 100% |
Near Mint | 90% |
Very Fine | 80% |
Fine | 60% |
Very Good | 40% |
Good | 20% |
Fair | 10% |
Poor | 5% |
For calculations the value of the qualitative elements is taken as a percentage of the 'base' Mint cost,
For example a 'widgit' listed at £100 is valued at Mint condition, a Good 'widgit' would be 20% of that so valued at £20.
Price Matrix
For each item that is to be graded (marked with *), calculate the cost based on the quality grading percentage, note that each item may have a different quality grading.
For items marked with # see exceptions further down the table.
Add up all relevant items to get a total cost.
