Euro Denomination Weight Lookup

Bounded nominal euro circulation coin mass reference in grams for eight denominations. ECB, technical specifications. Not measured tolerance, proof of composition or coin authentication.

Description

Nominal coin mass is a specification for an identified denomination, not an assay or authentication result.

Nominal coin mass is a specification for an identified denomination, not an assay or authentication result.^{[1, 2]}

This lookup explains the chosen topic using a bounded stored reference.

When to use Euro Denomination Weight Lookup

Use this tool to read a bounded explanation for an exact reference topic. Establish the coin issue, source edition, measurement basis and reference date where applicable.

How to use Euro Denomination Weight Lookup and understand its results

Establish the coin issue, source edition, measurement basis and reference date where applicable.
Enter denomination, using the field meanings and rules below, then run the tool.
Read result. Inspect nested result fields where present, and review unknown records separately from known matches.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
denomination	Denomination	string	Required

Select an exact denomination token from the table. Return its fixed nominal mass in grams; there is no measured input, tolerance check or issue lookup.

Selection token	Stored value
1cent	2.30
2cent	3.06
5cent	3.92
10cent	4.10
20cent	5.74
50cent	7.80
1euro	7.50

Limitations and assumptions

Coin identification, reference applicability and measurement uncertainty require separate evidence. A returned explanation or arithmetic agreement does not establish authenticity, a certified grade or a current market value.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.

Alternative or Complementary methods

For a related step, use Euro Denomination Diameter Lookup: Coin diameter is an issue specification distinct from mass, thickness and measured wear. For a complementary comparison, use Tolerance Band Compliance Checker: A tolerance band has both lower and upper limits, which can differ from a symmetric nominal tolerance.
