Frequently Asked Questions

What is the most valuable Standing Liberty quarter error?

The 1918/7-S overdate is the most valuable, ranging from $1,000 in low grades to $10,000+ in higher grades. It is one of the top US coin overdates.

Why do Standing Liberty quarters have no dates?

The date sits on a high point of the design and wears off quickly in circulation. Coins from 1916-1924 are especially prone to this. The design was modified in 1925 to recess the date.
