Quote: "ArnoV"I think the date reads התשמ׳׳ז (5747) which makes 1986.

Look at the character with the red arrow. It's 5767 (2007)

It's 5766. 2006.
It isn't. It's 5767 (2007) but the mistake isn't yours. There is a mistake in our catalogue for the KM# 163 (

ALL the AD dates are wrong and must be one year later. The dates in Jewish Era are correct.
By the way, the coin from
paveltul is not KM# 163 but KM# 160a (
