Need to add currency. [opgelost]

It was issued and used as limited currency within the amusement park.
Therefore, we think it is necessary to add a new “西武園(西武園通貨)＝SeibuEn (Seibuen currency)”.
I would appreciate it if you could help me.

It's En, not Yen.

What do you need help with exactly

i added my first exonumia a few months ago if you want to reference

Pretty bare bones
