This is the variant where attribution matters most. CIS separates the overdate premium from normal 1680 bust pricing, but it still requires clear visual confirmation before being valued above a standard crown.
Overdates are useful evidence of die use and mint transition. On this coin, the key recognition point is the final date digit, where traces of the underlying 9 may remain within or around the 0.
Description
The 1680/79 Crown is a standard-circulation Charles II silver crown variety where the date 1680 was struck over an earlier 1679 date. CIS treats it separately because the overdate is market-recognised.

Frequently Asked Questions
How do I recognise the 1680/79 Crown overdate?
Use magnification on the reverse date. The final 0 in 1680 should show traces of an underlying 9. If the overdate is not visible, classify the coin by bust type instead.
