It's a 100 yen coin, but I can't figure out what year

Blurry pictures but looks like your second image has maybe 25 on there

then if so is 25 (2013) and welcome to the site.


I added another year 25 coin to see what the numbers look like in comparison.

The two western numerals indicate the year within the particular reign.
I cant make it out in your photo too dark and out of focus, but
look for that number in this table

or this one

Welcome to the site!

You might want to work a bit on that camera focus....

Hmmm. Looks like 昭和35年(1960) to me but I don't think 100 yen was this design at that time...so probably 平成25年 (2013) or 昭和55年 (1980)?

I can confirm it is a 昭和 (Showa). I think it is a Showa 55, therefore (1980, very common).
