Some people who recently bought a discontinued nostalgic whisky that was brought back to shelves have found unexpected gifts inside, it is being reported.

Captain Q, a whisky that enjoyed massive popularity in the 1980s before being discontinued in 2015, was re-released this year with different ingredients and aging methods.

To celebrate its return after 11 years, a special limited edition set was introduced, containing two bottles of Captain Q, dedicated glasses, and a commemorative coin.

However, out of a total of 12,000 sets, 1,980 sets contain pure silver commemorative coins weighing about 1.5 don (approximately 5.625 grams) instead of regular model coins.

Naturally, there is no way of knowing whether a pure silver coin is included before opening the product.

The probability of finding a pure silver coin is about 17 percent.

Recently, these silver coins have been listed on second-hand trading platforms for prices ranging from 100,000 won to as high as 180,000 won, trading at a much higher price than the 20,000-won liquor set itself.
