Help needed--do these errors have any extra value

hello. First time here from the currency side. I have these 2 proof coins--a 2005 quarter and 50 cent piece. Are these errors significant enough or what? Any help is appreciated.
this has a small die crack: It is a West Virginia coin



I do not know what you would call this one:

it might have a premium to an interested Kennedy
collector, or a small premium to an error collector.
The line on the Washington Quarter doesn't really
look like a die-crack, from what I can see. It's either
some type of residue, or possible a thin piece of
plastic/cardboard/? that's on TOP of the surface of
the coin.
If it turns out to be a die crack, then yes, it has a
premium - I'd guess $20-$30 or so.
Hope this helps.

But I see both marks end (or start) at the rim... which supports what you are saying that they are a die crack or....
If the marks are raised metal, they may be die gouges. A die crack usually is not so bold and straight. If it was a die gouge, there would likely be some collector value.
Another possibility would be a strikethrough, with the items still retained in the coin. But this seems less likely to me due to the fact the item stops abruptly right at the rim; could be just a coincidence but a strikethrough would possibly have shown on the rim also.
So it is hard to tell without a closer look, etc.
Most likely residue.

I do not know the proper terminology for this type of error or any potential value. I would think there would be some value, especially with the larger piece still attached. Neat find!
