Matteo I think you have a lot to bring to this forum, don't worry about English being your (presumably) 2nd language! Peter can be very cryptic, but in this case 'ticks all the boxes' is a common English phrase. It means that all the criteria you are looking for in a coin are met (boxes ticked). e.g. grade, eye appeal, balance, mm, mint, moneyer, rarity, price, etc, etc
