A tiny dot on a coin can make a big difference—in fact, it is the distinguishing feature of a true rarity: Canada's 1936 Dot 10-cent coin. With only six known examples in existence today, the uncommon coin is the kind of ultra-rare, high-value find that puts any collection into a rarefied stratum, and transforms a collector into a custodian of history. Both the obverse and reverse designs have been pain stakingly replicated, and all the original details have been kept intact—even the "1936" date on the reverse. And that's a first for us, because the year of issue usually takes precedence.
