username18333; Nietzches analysis of value was interesting. Must read him (at some point in the distant future 
).
The connection between value and price:
Value depends on the individual valuer (the subject), according to what supports his life best, everything (in his life) taken into account.
When each valuing individual starts to trade, the result of each trade is a price. The price is historical only, because the valuations change instantly and partly inconcient (using fast thinking). A price is expressed as a pair, apples can be priced in cows, and cows in apples. Money is also such a thing that is valued individually by everyone. Since money is practical for exchange (that is why those things are called money anyway), we see prices expressed in money a lot. And with many traders in the same arena, we have a market.
The (historical) price of something is a guideline for every trader. If he knows the price of yesterday, he knows the approximate value that others placed on the thing in the past. Therefore he can calculate, and it is also quicker to find the bid or ask point that is likely to succeed with an executed trade.
tl;dr Value is individual. Price is historical, exposes others' valuations.
