Roll Notes: 2024-P Quarter Dr. Mary Edwards Walker WDDO-001

ByGeoff W.

This 2024-P Dr. Mary Edwards Walker quarter turned out to be a confirmed WDDR-001 doubled die reverse, complete with all published die markers. The most obvious feature is the extra raised hair detail behind Walker’s right shoulder, which does not appear on normal strikes and is easy to verify against official Mint images.

In this Roll Notes entry, I document the doubling, walk through the diagnostic markers, and show how this variety can be confidently attributed using both photographs and in-hand inspection.

Roll Notes: 1996-P Jefferson Nickel – Spiked Head (SKH-5c-1996-p-04) Die Crack

ByGeoff W.

A 1996-P Jefferson nickel showing a documented Spiked Head (SKH) die crack variety. The crack begins at Jefferson’s nostril and runs diagonally across the face, passing above the vertical bar of the E in WE. This example matches the known die markers for the SKH listing and was found during roll hunting.

Wide AM vs. Close AM: How To Spot the 1998–2000 Lincoln Cent Reverse Variety

Two different reverse designs were supposed to stay in their own lanes. They didn’t. Old dies slipped back…

How Off Center Does a Coin Need to Be to Have Value?

ByGeoff W.

Off center coins are some of the easiest dramatic mint errors to spot, but not all of them are valuable. This guide breaks down how they happen, how to judge the percentage of the strike, and what actually matters when figuring out if one is worth keeping.

Grease Filled Dies: Why Your Coin Looks Half-Faded

ByGeoff W.

When a coin looks weak or washed out in random places, most people think it’s worn down. Sometimes they’re right. Sometimes they’re not even close. This is a grease filled die. It happens when mint machinery gets clogged with thick gunk made of metal shavings, old oil, and debris. That paste fills the recessed parts…
