Hi.  Welcome.  There is more than one possibility.  Let us see a photo.

German handmades circa 1900. two in top left of pic look to be above average in terms of desirability but condition is important.

No onion skin marbles.

I also have some marbles that appear black but show color in them when "candled". The ones pictured show dark burgundy. I have at least two that show blue and one that shows pink. You can see no color in them without the light.

@Yupimagirl, do yours have an iridescent finish?  That would be a sign that they were modern, probably from Asia or possibly Mexico.  Possibly a decorative glass, though possible still planned as a toy marble.  If not iridescent, then really dark "clearies" and hard to tell the age.  Could be, say, 50's.  Or could be this century.

Most, if not all, do have an iridescent finish to them. I do have clearies as well, in blue, green, red, burgundy, purple, pink and amber. Some of those also have an iridescent finish. I'm learning so much. Thank you.
