"Word Ladders" change one letter at a time at each step while maintaining the exact order of letters of the previous word:

B I G
B I T
B A T
C A T
In Laddergrams these were the rules:

At every step only one letter may be changed.
Once changed you have to keep that letter.
All letters from the previous word must occupy a new position, in effect we create an anagrammed proper word of those letters but with one replaced.

S P A N
P A N T
T R A P
R A T E
T I E R Note that, in the above, A and T each occupy the same positions in more than one word.

New rule!
No letter may ever occupy a position it has already occupied.

Your task is to change PANT into currency.

P	A	N	T
Y	Y	Y	Y
Y	Y	Y	Y
Y	Y	Y	Y
Y	Y	Y	Y

Having done that, are you able to create such a ladder of your own?
