Need ID for seeds

[HoneyBerry]

I saved some seeds and forgot to lable them. Does anybody recognize the seeds in this picture?

[applestar]

How big are they? You have no clue at all?

FWIW, my guess is grape seeds.

[HoneyBerry]

Yes! I think they must be Concord Grape seeds. I remember now. The concord grapes were so good, so I was saving the seeds to grow some in my yard. At first, I was thinking they might be seeds from one of the heirloom apple types that I tried, but apples don't have very many seeds in them, and I saved so many of these seeds. I'm pretty sure they are grape seeds. Thank you, Applestar. Your knowledge is so valuable.

Yes, grape seeds.
