Thank you for offering to help improve this plating study! Please provide details about your 13L4 stamp below. I'll respond as soon as possible to discuss purchase or trade options.
January 6, 2026: Today is my 72nd Birthday and I'm proud to announce the launch of Version 2 of www.stampplating.com. This is a Major Update - After almost nine years, we've completely rebuilt this plating study with double the platings, powerful new tools and a unique visual experience to help you identify your 3¢ 1851 stamps!
What's New:
Start with the Plating Wizard or read the Wizard Guide to learn the systematic approach.
This study is dedicated to helping you plate your stamps!
⚠️ PLEASE HELP! These stamps urgently need better images or plating corrections.
I have never heard of a plating that is perfect - but I want this one to be!
If you have one of these stamps for sale or trade, please contact me!
I'm actively looking to purchase these positions to improve the accuracy and completeness of this plating study.
These positions have been identified by philatelic experts as needing better images or plating corrections. I am actively seeking to purchase or trade for these stamps. Your help in locating these positions is greatly appreciated!
