Since it's the monetary value of the sign that Claude "lost", she felt that it's only fair to give him an equally important keepsake of her own. At that point, it was Claude who decided to sell it since he had no wish to keep it.
She seemed to be awfully moved when Claude promised to get it back. If she considered it a mere financial compensation, nothing more, I think she would have insisted it was a fair trade and Claude doesn't need to strive to get it back. I admit I might have used too strong expressions, but I deem at that point she was far from sure if she's allowed to stay or not. The last words from Claude were that she should return to Japan. So, she obviously went for her most precious possession. Besides, she's still a kid.

In reality people were still being treated like dirt in the 19th century, so I'm happy this show necessarily isn't all that realistic and Yune gets pretty friendly and gentle treatment, making this a joy to watch.
