This bust of the queen was introduced in 1999 and still appears on the twenty cent piece. This is the regular issue, altho this denomination is frequently used for commemoratives.

Recorded mintage: unknown plus proofs plus 1,966 in silver plus 100 in gold.

Specification: 11.31 g, copper-nickel, 28.65 mm diameter.
