If you have an old iPhone 1 sitting around that you want to sell, then knowing how much to charge for it will help you sell it quickly while still getting the best price for it. If you look for other iPhone 1 models for sale at places such as eBay or Craigslist for all different pricing from $10 up to $150 depending on the iPhone 1 available storage space or what sort of shape it is in.
You do have a much better chance at getting the best price if you sell it outright than selling it to companies who buy cell phones. For example, at places such as NextWorth, an iPhone 1 with 16 gigabytes of storage that is in good condition is only worth $5.00.
