1/20 oz Libertad Silver Coin

The 1/20 oz Silver Libertad

The 1/20 oz Silver Libertad is the smallest coin in Mexico's silver bullion series, containing just 1.555 grams of .999 fine silver in a 16mm diameter coin, roughly the size of a small shirt button. It is struck by Casa de Moneda de Mexico (founded 1535) and issued as legal tender with no face value, following the unique Libertad convention where the coin's legal tender status is guaranteed by Banco de Mexico at the market value of its metal content.

At 1/20 of a troy ounce, this coin exists at the extreme edge of fractional silver. The silver content at current prices is worth only a few dollars, which means the production cost, packaging, and distribution expenses represent a large multiple of the metal value. Premiums on the 1/20 oz Libertad are accordingly steep, often exceeding 50% above spot on a per-ounce basis. This is not a product for buyers seeking cost-efficient silver accumulation. Its appeal lies almost entirely in collecting and completing the full eight-denomination Libertad silver set, which ranges from this 1/20 oz coin up to the 1 oz and beyond to the 1 kilogram format.

The Libertad's consistently low mintages compound the premium picture. Casa de Moneda produces far fewer coins than the US Mint, Royal Canadian Mint, or Royal Mint, and the fractional sizes are the most limited of all. Some year-denomination combinations for the 1/20 oz have mintages in the low thousands, making them genuinely scarce by sovereign bullion standards. For collectors who track Libertad production numbers, these fractional coins represent the hardest-to-source pieces in the series.

The reverse carries the Angel of Independence (Winged Victory) with Mexico's twin volcanoes Popocatepetl and Iztaccihuatl in the background, the same design as the larger denominations. The obverse features the Mexican coat of arms, with post-2000 issues showing ten historical versions of the arms in a surrounding ring. The high-relief detail is impressive for such a small coin, though the full design complexity is best appreciated under magnification.

1/20 oz Silver Libertad Specifications

Size Comparison Within the Silver Libertad Series

The 1/20 oz is the smallest of eight silver Libertad denominations. The full range spans from 1/20 oz (1.555 g, 16 mm) through 1/10 oz (3.11 g, 20 mm), 1/4 oz (7.78 g, 27 mm), 1/2 oz (15.55 g, 33 mm), 1 oz (31.1 g, 40 mm), 2 oz (62.2 g, 48 mm), 5 oz (155.5 g, 65 mm), and 1 kg (1,000 g, 110 mm). The 1 kg coin is one of the largest legal tender silver coins in regular annual production from any sovereign mint.

1/20 oz Silver Libertad Tax Treatment

United States

IRA eligibility for the Libertad is uncertain. The coin is not specifically listed in IRS Section 408(m)(3)(A) alongside Eagles, Maples, and Britannias, but .999 silver bullion coins may qualify under the generic bullion provision depending on custodian interpretation. Given the very low silver content (1.555 g), IRA inclusion for this denomination is unlikely to be practical in any case. Federal capital gains are taxed at the collectibles rate (up to 28%). Most states exempt bullion from sales tax.

United Kingdom

Subject to 20% VAT on purchase. Not CGT-exempt (not UK legal tender). The 20% VAT on a coin with such low metal content makes the effective tax burden proportionally extreme. UK buyers seeking fractional silver with better tax treatment should consider the 1/10 oz Silver Britannia, which is at least CGT-exempt as UK legal tender.

Canada, Australia, New Zealand

Silver at .999 purity is GST/HST exempt in Canada, GST-free in Australia (investment-grade), and GST-exempt in New Zealand. The tax treatment does not vary with the denomination size.

Singapore and Hong Kong

Singapore's IPM scheme covers silver at .999+ purity from recognised mints, including Casa de Moneda. Hong Kong has no sales tax or CGT. Both are fully tax-neutral for this product.

European Union

Standard VAT applies at each country's rate. No investment exemption exists for silver. Margin scheme may apply on pre-owned coins in Germany, the Netherlands, and Spain.

1/20 oz Libertad vs Other Micro-Fractional Silver Coins

The 1/20 oz denomination is extremely rare in silver bullion. Almost no sovereign mints produce silver coins this small, because the metal value is so low relative to production costs that the product makes little sense as a bullion investment. The 1/20 oz Libertad exists primarily as a collector piece to complete the series.

The closest comparison is the 1/20 oz Silver Britannia (10p face value) from the Royal Mint, though this coin is produced in very small quantities and is difficult to source. Both contain 1.555 grams of .999 silver, but the Britannia carries UK legal tender status and CGT exemption, while the Libertad has no face value. In markets where CGT matters (principally the UK), the Britannia holds a structural tax advantage. In terms of collectibility and secondary market premium, the Libertad's lower mintages generally support stronger demand among series collectors.

Compared to the 1/10 oz Silver Libertad, the 1/20 oz contains half the silver in a noticeably smaller coin (16mm vs 20mm). The per-ounce premium is higher for the 1/20 oz, and liquidity is lower. The 1/10 oz represents a marginally better balance between fractional Libertad collecting and actual silver content. For buyers choosing between the two, the 1/10 oz is the more practical option; the 1/20 oz is for completists.

Against full-size 1 oz sovereign silver coins such as the 1 oz Silver Britannia or the 1 oz Silver Maple Leaf, the premium comparison is dramatic. The per-ounce cost of silver accumulated via 1/20 oz Libertads could be double or more the cost through 1 oz coins. The 1/20 oz Libertad is not a vehicle for building a silver position; it is a collectible, a gift, or a curiosity for Libertad enthusiasts.
