Ooh, I collect those, too.
The HTH one has to be from Disneyworld - that's the only one that went by Hollywood Tower Hotel (versus Tower of Terror, which was the Disneyland designation.)
I think the ones that don't have park names on them (Piglet, Tinkerbell) were available in multiple Disney parks.
I also think the gold ears are Euro Disney.
Disneyland's 15th would have been 1970.
Disneyworld does their anniversary by parks (and Magic Kingdom's was in 1986.)
I have a similar Disneyland ones from their 60th.
