FIVE DISTINCT CASH UNITS
Compare fine gold, diameter and liquidity—not the size label alone
The Gold Vienna Philharmonic ranges from one ounce to one-twenty-fifth ounce. All five current sizes are Au 999.9 and the 2026 programme gives none a maximum mintage. The practical choice is about all-in cost per fine ounce, unit size, handling and the bid available when you sell.
OFFICIAL COMPARISON
Current fields and first-issue dates
| Size | Fine gold | Published fine weight | Diameter | Euro face value | First issue |
|---|---|---|---|---|---|
| 1 oz | 1 oz | 31.1 g | 37 mm | €100 | 1989 |
| 1/2 oz | 0.5 oz | 15.55 g | 28 mm | €50 | 1994 |
| 1/4 oz | 0.25 oz | 7.78 g | 22 mm | €25 | 1989 |
| 1/10 oz | 0.1 oz | 3.11 g | 16 mm | €10 | 1991 |
| 1/25 oz | 0.04 oz | 1.24 g | 13 mm | €4 | 2014 |
The one-ounce and quarter-ounce coins began in 1989. The tenth followed in 1991, the half in 1994 and the 1/25 ounce in 2014. Do not assume a size existed in a year before its documented first issue.
UNIT RECONCILIATION
The smallest coin shows why rounded displays need restraint
One twenty-fifth of a troy ounce is about 1.24414 grams, while the Mint displays 1.24 g and 0.04 oz. Those are consistent rounded product fields. A page should not manufacture extra decimal places, an assay result or a mint tolerance that the issuing source did not publish.
For value, use the stated 0.04 fine troy ounce. For physical screening, compare the exact year and product with official records, calibrated tools and professional judgment rather than treating a rounded web table as a certification standard.
BUYER MATRIX
When the “best” size changes
Less cash needed per purchase.
Simple per-ounce quote comparison.
Sell part without breaking a larger unit.
Compare actual ask and bid per ounce.
A smaller coin is not automatically cheaper: its sticker price is lower because it contains less gold, while its percentage premium may be higher. Normalize every quote to fine ounces and include fixed delivery, payment and resale costs.
