Prices as hash output - that's brilliant and makes perfect sense to me as one familiar with cryptography. I'll try it out on some others who are not so familiar with cryptography and see how it goes.
Hash outputs aren't unique because the hash is generally smaller than the input (probably not true for passwords but hashing preceded those). It is definitely possible for two passwords to produce the same hash value but the important fact is that it is very, very difficult to determine a valid password from the hash.

Fantastic analogy.
