Peter,

You will need to look for new cards in figure skating. Hamilton and Yamaguchi cannot hold an ice cube to some of the greatest figure skaters of all time:

Males

All time

Gillis Graström of Sweden - 3 gold and one silver in the Olympics, 3 golds World Championships (1920-1932). He is technically the first person to win a gold medal in the Winter and Summer Olympics. Figure skating was held during the 1920 Summer Olympics in Antwerp. The first Winter Olympics were 4 years later in Chamonix, France.

Modern

Yevgeny Plyushchenko - 2 golds and 2 silvers in the Olympics. One of the golds was Team Mixed skating in 2014. At the World Championships - 3 gold 1 silver, one bronze.

Females

Sonja Henie - 3 Olympic gold World Championships - 10 golds 1 silver

Irina Rodnina (pairs skater) - 3 Olympic gold World Championships - 10 gold
She won her first Olympic gold and 4 World golds with Aleksey Ulanov. He became romantically involved with another skater. Rodnina switched partners to Aleksandr Zaytsev, whom she married in 1975. Together they never lost a competition - 2 Olympic golds, 6 World Championships and 7 European Championships.

Grafström is in the Zeenut UV light set and Idrottsbladets Bildgalleri (Swedish set sort of like the Reemstma set). Also on some postage stamps.

Henie is in the 'Greatest Olympians" set, Sportscaster, SI for Kids, 3M Innovators, Reemstma (aka Sammelwerk, aka Olympia) and others.

Plyushchenko (Plushenko) is in the 2020 Euroset year in sport set card #16.

Rodnina is in Sportscaster, Brooke Bond, Soviet World of Sport, Zeenut UV light. I believe she is on one of the Soviet Heroes of Sport postcards issued after the Olympics. She is also on a few postage stamps.

For the greatest female Olympian there are a number of cards of Larisa Latynina - Brooke Bond among others. In tennis there are a number of Margaret Court cards. More grand slam singles titles and total titles than Serena Williams.
