.... Plug Difference?

[MX5]

What is the difference when a cart has a stem .... plug not attached to the cap and the one attached to the cap? I have gotten carts with both. Is one cart older than the other? This has probably been addressed before but I'm new and don't know the answer. Thanks to all who answer!

Hard Cap premiums have a tiny attached ....-plug and a small hole.
Soft Cap Premiums have an unattached .... plug (in the first generation) and a larger hole.

Hard Cap Regular Second-Gen have an attached ....-plug.
Hard Cap Regular First-Gen have an unattached ....-plug.
