How common are filled letter/numbers?

Hello all,
Just a general question - if this is in the wrong place i apoligize and please move it to the correct forum

How common is it to find filled letters and numbers on wheaties.
I have gone thru a bunch and have found what seems like a lot of these types of "errors".

Do they have any added collectors interest or add any extra value to the coin?

Thanks

Pretty common, but not a lot of collectors or added value.

Thanks Guys
Kind of figured that based on the amount of them I found. Still a cool find for me though.
