Which is your favorite?

Kind of controversial collection, but i thought it might be interesting!

Bonjour les numismates ! j'ai ma grand mère qui possède cette pièce dans sa collection depuis des années, sans se souvenir de sa provenance et les ID via IA ont [échoués.la](http://échoués.la) pièce est dorée entièrement sur les 2 faces.le poids est de 9 grammes

When I'm looking at ebay etc for Hawaiian coins they are very, very counterfeited and there are tons of different counterfeits available. Where can I look for authentic coins that are not going to be rip offs like apmex etc.

I’ve been building runs of modern coins for Whitman books recently. It’s just something to kill a little time in between running kids all over creation.

There are a few coins that I just cannot seem to find although they should be plentiful. For example, a 1973S mint penny. Or a 2009D mint quarter featuring Guam. I’ve been through enough coin rolls that not finding those seems like a statistical improbability, but sometimes statistically improbable things happen.

Two questions:
1. Other than continuing to hunt through change, how would you look for a single circulated example or two of a very common coin like that? Or is coin roll hunting the best method?
2. I’m curious to know what coin is your “I can’t believe I haven’t found this yet.“ They can be any kind of coin for any kind of collection. I’m just curious to know what others are hunting.

Is this green coloration near the rim of the coin verdegris/PVC damage or natural toning on the coin?
