It would be interesting to approach this question in a different way and think about what we would have forgotten in 200 years about life today and then to answer it based on that. For example, would we have forgotten day to day life and the jobs that we have to do without the technology that will no doubt be developed to make our lives easier in the next 200 years? Would a diary of a housewife be of interest in this situation?
How about a classic car in mint condition? If it belonged to someone famous, say...Hitler, for instance, that would be even better if the documentation which proved the ownership were included.
I think you need to determine your definition of valuable. As the first poster said gold will most like maintain its value, other antiquities will also maintain their value. Other posters have offered things such as technology items that while they may not be of value two hundred years later would certainly be of interest.
Maybe the first generation of new techology. Early personal computers are worth a fair amount, from what I understand. Whatever I buried, I would make sure it was kept in an air-tight, waterproof container!
As others have said, gold would be my first choice, because it backs global currency, and its value has been recognized by almost every culture, past or present.
I would also bury maps to as many fresh water sources as possible or some type of water purification system--since water is something that all living creatures need, and it could very well be in short supply.
You could bury personal items belonging to the most influential people of our time. Anything people would pay money for from Obama, or Nixon, or Stalin. Imagine what a highly personal item from Abraham Lincoln is worth today. Anything from Einstein would work, too.
A treasury bond would be worth a lot of money in 200 years because they gain a lot interest.
Books in general may also be worth a lot of money because people are turning to devices such as ebooks. Certain books will be much more valuable than others but eventually books will be manufactured less and less.
I'd bury an iPad. I think it would be really interesting for someone from 200 years in the future to see what we thought of as futuristic at this point. And I think that it would be way more valuable than gold in terms of being a one-of-a-kind relic from the distant past of technology.
What about an American history book. This would serve two purposes. 1)It would give those in the future an understanding of where the country had been. 2)It in itself would be revealing as books might be a thing of lore by that time.
A good watch, especially if it is a gold one, might be a very delightful object to retrieve in 200 years. If it is a good watch it is likely that it will stop the moment it is removed from the wrist, so you will be able to estimate at what time it was placed in the "time capsule"- In fact, you just gave me a good idea- mine will have to be a cheap watch though ;)
First, I believe gold will continue to rise in price, and presumably, the world gold standard will still be in effect. Being an avid follower of The Antique Roadshow, I believe any valuable old porcelain (or other rare items that would survive underground, such as oil paintings or jewelry) will only become more valuable in 200 years.
I definitely agree that gold and other precious metals will definitely be valuable in 200 years. Surely by then it will all be mined out and will be exceptionally valuable. I would also bury some books, such as the Harry Potter series and Hunger Games, just so they can see what teen lit was like back then. An interesting question, thanks for asking!
I would bury;
My iPod (so that future generations can see what technology was in the 21st Century)
My MacBook White (they might have something more incredible than laptops in the future)
My CD Collection (with us being able to download music from the internet will probably end the usage of CDs)
The Official Michael Jackson Opus (or maybe not, I'd rather pass that down for future generations)
A Queensland or Australia Map (roads will definitely change in 200 years. I'll bury our flag as well, since the debate of removing the Union Jack was a big topic, maybe by then, we'll finally replace it with the indigenous flag or something)
And lastly, some Australian notes and coins (money would look different in the future, and of course they would be very valuable. I'll make sure to keep some in the family as well).
I love your question. Great way to start a discussion or conversation, as it was a fun topic!!
And.....Hitler never had a car, thats why he neeeded someone to drive him around during the world war. He had no licence
a penny....tv....watch.....computer.....gold coins.....all that junk inside your hubands dresser...lol
