I was on 9 tokens in the past crate event. My faction has completed the faction HQ to 10, one of those 'rewards' of doing so is a 3% chance at getting x2 tokens opening a crate. During my next open I got x2 tokens, putting me at a total of 11 tokens. Doing so did NOT grant me the prize for achieving 10 tokens - which is the one that counts because it has a boost.
