How do reserve price auctions work?

Some auction items (excluding No Reserve Auctions) may have a reserve price.

This simply means that the seller has a pre-set bid amount that must be matched or exceeded. The reserve price is hidden, however it states at the top of the item if the reserve has been matched or not. Additionally if you place a bid on a reserve price item, you will be notified if you met the reserve price.

If the reserve is not met before the auction closes, any bids will remain, however the auction will restart its countdown and will remain unsold. This is why you may see some auctions that have bids from a long time ago.
