Different question. The answer from dedicated collectors will not surprise you: yes, this is a fun start of a collection. The real question is therefore, are you motivated to collect coins? If you are not sell them, take the handful of dollars and let someone else enjoy them. If you are, these coins will repay you many times over as you try to understand them down to the flimsiest detail.
They'll teach you to bargain, to appreciate beauty, to read foreign words, geography, foreign scripts, metallurgy, they will improve your photography, your network of friends and acquaintances, your knowledge of history and postal regulations and even your ability to surf the net. It's up to you now.
