4 Apple iPhone (First Generation)

The original iPhone is only ten years old, but it’s already fetching a premium on eBay. One seller has a factory sealed iPhone listed for $6,650. The same seller sold another iPhone for $5,820 in 2016. The original iPhone — sometimes called the iPhone 2G — is hard to find in mint condition. As the iPhone played such an important role in the smartphone revolution, it’s very possible that $6,000 is a bargain.
