Coin Collectors I need an answer?

If you mean get a newly-discovered variety listed in the Red Book, first, it has to be recognized as a new variety, and it won't reach that status until it's found that there are a more than just a few of them. Otherwise, it would be a mint error. You'd also be seeing write-ups in weekly/monthly coin publications long before Red Book, which comes out once a year, picked it up.

After doing some looking around, I found several references to New Hampshire quarters with 'missing' mint marks, and they appear to be filled-die errors. Grease temporarily fills certain areas of the dies, which doesn't allow some or all of the metal that would normally 'flow' into that recess during striking, creating that particular feature. Apparently this is quite common with the state quarters in general - there are more different error types with this series than with any other, in fact, an entire book could probably be written on State quarter error types.

Given this, it will probably never make it into the Red Book as a variety. You'll have to see what the label on the slab says when it comes back, if you do send it. My opinion is, currently, the cost of grading far exceeds the value of the coin. But it's up to you. The only thing with coin collecting that never changes is the fact that things always change.

These days, starting 1990-91, the production hubs have the mint marks on them. So in the end you have a quarter that was damaged out side the mint or maybe some grease filled the die over the mint mark. Before spending money to have the coin returned ungraded and in a body bag you should show it to a few coin dealers. It is not uncommon for coins to be missing parts of the legends or dates due to oil, grease or a piece of rag getting on the die. I have some Delaware quarters with the word "the" missing in the motto the first state, they are interesting but have no added value. As for the Red Book, it takes a long time to have a variety added to it. The coin collecting community must support the find first.
