How rare is this type of domain really?
3 of a kind and another 3 of a kind?
111222
for all sets beginning with 111 (excluding 111 at the end)
that's 9 sets times 10 sets equal 90 possible permutations similar to this.
Beginning with 222,333,444,555,666,777,888,999,000.
that's pretty rare.
if you exclude all the 444's and the 000's that's 18 sets total.
90-18= 72 possible combos of lucky numbers or "okay" numbers.
No wonder it is up there in price. $100K is reasonable best guess.
