5 Yen and 10 Yen Showa-era Japan

[Verify-12]

Just picked up these two coins from a coin show.

I scanned both coins here as they were still inside their original mylar 2X2 holders, so you'll see dust on them.
They are both in Mint State condition of some sort.  I'm guessing at LEAST 64.   I will get them both graded by Numismatic Guarantee Corporation (NGC) sometime.  These coins are practically impossible to find in this condition.   I paid $50 USD for the 1955 10 Yen, and... you won't believe it, but... $12 USD for the 1957 5 Yen.  Yes, really!   This coin has a mintage of 10,000,000 pieces, the lowest for the 5 yen.

5 Yen, Showa 32 (1957) on the top.
10 Yen, Showa 30 (1955) on the bottom

JNDA (2008) lists the 10y and 5y at 25,000y and 15,000y, respectively. Typically the catalog values are inflated between 3-5 of the actual market value. Definitely not a bad buy!
