How to use this tool
- Name the pattern or set and enter the budget you want to spend on replacements.
- Open Piece details and update required counts, owned counts, and typical replacement prices.
- Review overall completeness, specific shortages, and estimated cost to complete the set.
How the result works
Completeness is calculated from the smaller of owned quantity and required quantity for each piece type, so extra spares do not make a set more than complete.
Replacement prices are your estimates. Matching a specific pattern, date, maker, finish, and condition can matter; a visually similar piece may not complete a collector’s set.
Frequently asked questions
Does a complete set always have higher value?Not always. Maker, pattern rarity, condition, provenance, and market demand can outweigh completeness.
Why are extra pieces not counted above 100%?The metric measures required pieces filled. Surplus pieces may be useful spares but should not inflate the set-completeness percentage.
Are replacement prices fetched from a marketplace?No. Enter the price you observe or receive from a seller; no current listing price is assumed.
Can the tool authenticate a pattern?No. It tracks quantities and budgets only. Confirm the maker and pattern using marks, catalogues, and reliable references.
How should I handle a missing rare serving piece?Enter a realistic replacement estimate and consider that price uncertainty may be greater than for common forks or spoons.
