If you are talking of value, we should first of all considered acceptance of commodities. Values comes when the item or a commodity is widely acceptable. Your items, goods or commodities will not be valuable when there is no acceptance.
This also apply to cryptocurrencies, once the coins is widely acceptable this will be push up the value and hence, price will be determine. You can offer your items with any amount of price, but if the items lack willingness and acceptability nobody will go for it at any price.
