2001 is the year China switched the Gold Panda's sizing convention from troy-ounce fractions to metric gram weights — the modern 1g, 3g, 8g, 15g, and 30g lineup, with 30g now the standard "1 oz-equivalent" size. This is a specification change, not just a design refresh, and it's the single most common point of confusion for Western buyers comparing a Panda's weight to an ounce-denominated coin from another country.
When comparing a 2001-or-later Panda's price to a 1 oz coin from another series, remember 30 grams is about 0.9645 troy oz — slightly less than a full ounce. Pre-2001 Pandas use the older troy-ounce sizing and aren't directly size-equivalent to their post-2001 counterparts of a similar nominal size.

Almost, but not exactly — 30 grams is about 0.9645 troy oz, slightly less than a full troy ounce (31.1 grams). Worth accounting for when comparing prices to ounce-denominated coins.
