I wouldn’t. Sure, there is an off chance that someone might find this to be an interesting curiosity in 10 years. But technology-wise, it is already out of date and will continue to get even more out of date. So even if the look/feel is a museum piece, it will never work as an effective phone in the future. Keep in mind that the battery will deteriorate over time as well. At some point, no matter how much care you take, it won’t take a charge any more. So you won’t be able to power it up anyway, after a while. Summary: not worth it as a collectible.
