Obverse: identify the front

Wilhelmina faces right wearing a tiara, surrounded by KONINGIN WILHELMINA GOD ZIJ MET ONS. Read the monarch’s name along with the portrait. Earlier young-head coins face left, so portrait direction alone must not be used to reject a correctly attributed earlier Wilhelmina issue.

Reverse: identify the back

A crowned shield with the Dutch lion divides 10 and G. The date 1911 sits below; KONINGRIJK DER NEDERLANDEN surrounds the arms. The numeral is a useful denomination check. Preserve small privy symbols and the rim in a full photograph rather than cropping identification details away.

History and purpose

The reference’s type records distinguish the earlier young portrait, the 1911–1917 head-right group and the later 1925–1933 group. These are classification intervals with production gaps, not a statement that every year was struck. Keeping portrait types together with actual dates makes inherited Dutch gold easier to identify.

How to identify this variant

Look for Wilhelmina’s name, 10 G and the Dutch crowned arms. The matching reference record gives 22.5 mm diameter. Confirm the complete denomination before using this entry, because a similar portrait on a smaller gold coin does not establish ten gulden. Retain any original attribution for unusual privy details.

Understanding its metal content

The calculator follows the cited 0.1947 troy oz fine-gold amount; three correctly identified coins total 0.5841 troy oz. The separately reported nominal mass calculation is 6.729 g × 0.9 = 6.0561 g, or approximately 0.194708 troy oz. Published rounding can make these displays differ; the source precision note records the distinction. The calculator does not measure wear or determine an actual purchase offer.

Dates, varieties and composition changes

The 1911 illustration is a mature head-right example. Earlier young-head and later older-head designs remain separate subtypes within this denomination. The 1892–1933 endpoints are an identification span, not continuous annual production. Any overdate or unusual combination should be recorded rather than valued from a generic picture.

Melt value versus collector value

Preserve the portrait, date, privy symbols and surfaces when grouping coins. An older, unusual or well-preserved specimen can deserve individual review beyond nominal gold. A catalog interval does not establish rarity or a condition grade; avoid cleaning or assigning a premium solely because the coin resembles this reference.

Authenticity and condition

Read the denomination, both face designs, full date and mint details together before choosing a calculator entry. Keep photographs of the rim and any original holder with the record. Measure an intact coin using a suitable scale and caliper; do not clean, scratch or bend it to test the metal. Reference photographs illustrate a design and do not authenticate or grade another specimen. An unfamiliar date, mount or altered detail warrants individual examination.

Selling this coin

Keep this denomination separate from similar-looking smaller coins and from other alloys. Count only examples whose type has been identified; set uncertain pieces aside for appraisal. Record quantities, readable dates, mint details and both-side photographs using the existing quote form. The prefilled context helps identify the lot, while nominal metal content, collector assessment and any actual offer remain separate.

Sources and calculation methodology

The reference’s named world gold table reports 6.729 g, .900 and .1947 oz AGW. The calculator retains that reported AGW, while the nominal mass product is disclosed separately. The reference’s broader Netherlands row also covers a different ruler; this retained identity remains Wilhelmina only. The owner selected reference as the deciding reference when metal specifications disagree. Source photographs, their reuse rights and face assignments are reviewed separately. These are reference specifications, not a first-party assay or a current market quote. No approved live price feed is configured, so dollar melt values remain unavailable. Dates of review reflect actual editorial work.
