9 carat gold is harder because it is mixed with other types of metal which are harder than gold.
Gold is a fairly soft metal.
Historically cold coins were sometimes bitten to check how soft or pure the gold was . Another historical practice was to scrape or peel off the edge of the gold coin ( keeping it looking circular of course!) and collect these scraps for melting. This is the reason why nowadays coins are edged with serrated markings, called reedings..to prevent you from taking a little bit off the edge!

Even at 14k and 18k gold wants to be yellow
