Last year saw the 35th anniversary of the first Chinese Silver Panda coin in a series that remains hugely popular to this day. The annually changing designs have pleased collectors for decades, and with the numbers minted growing ever greater, that seems unlikely to change anytime soon.

It’s fallen to European producer AllCollect to mark the occasion with a special release and they’ve certainly done so with a sense of grandiose style. There are no shortages of Panda-themed coins, but this new release isn’t going to be confused with any of them. Tipping the scales at a kilo isn’t extraordinary in itself as the Bank of China have been issuing in that weight for years, so how do you stand out from the crowd. Diameter..

Stretching out to a colossal 180 mm in diameter, this is a coin like few others. The Perth Mint has its 10kg lunar bullion coins of course, which hit a huge 221 mm across, but not in the highly collectable proof finish. In truth, those lack fine detail as they’re effectively just the 1oz design enlarged to fit the bigger surface, but no such limitations here.
