There are more such sales in .ly alone, you didn't quote all of them. But the fact remains that Libya is not stable and the future is very uncertain. It has no functioning government while Daesh is making progress in the region and could further destabilize the country.
I don't think people always realize the risk. It's called doing your homework.
Please don't take it personally, I am only explaining (in answer to your post) why it can never be guaranteed that a domain will always continue to work, not matter what happens in the country of origin.
I am not saying your names will never sell, but an informed buyer will see the risk and will be more reluctant to make a nice offer. If the situation on the ground becomes critical, your domains could become useless. Countries like Iraq, Syria and to some extent Libya are disintegrating and may even cease to exist in the near future (no kidding). But I see that you are from Libya so you obviously understand that.
As to the domains, there have been reported sales indeed, but there are plenty of possible domain hacks in .ly and it's not like every single name is going to sell. I think hacks are more a lottery than an investment but good luck to you and be safe
