Just doing a google search I’m seeing these being sold at around $6 - $10. Scroll down on this page and you’ll see one quite a bit like yours for $9.99 https://www.nancyscollectibles.com/madeinjapan3.html
Etsy and eBay have similar ones as well. Note that there are different makers and so that could make a difference in value.
