With maple seeds in general you want to get these early, when they are fresh and soft. After they harden germination is much less eager.

Anyone who has them at this time of the year should have been stratifying them or otherwise storing them in such a manner (cold) that germination may be possible this spring. Otherwise you will probably be waiting until next year before any of them start to come up.
