Can You Help Me Identify This Button Material?

[SDIceMan]

Hi all. I found a 'large' bag of matching buttons while cleaning out an estate. Large as in 1000+. Are there any button experts that care to venture an educated guess as to their composition? I couldn't feel any seams so I was leaning towards ruling out plastic. The button face is polished smooth and the reverse has sort of a parallel grain. Thank you in advance.
