The needle may be loose on the pin. Or the cable frayed and is making 
weird readings.
Of the needle slipped, open up the speedo, there should be a black mark 
on the balance wheel, this is ZERO. Roll the balance wheel and watch the 
needle, they should move evenly, 1/2 way on the wheel should be 50 mph. 
3/4 = 75 mph. but it will go past 100.
Hold the balance wheel near 1/2 way and push the needle to 50 mph then 
push the needle down on the pin with a fair amount of finger pressure 
only, no BFH on the speedometer needle ;)
You can also move the needle by holding it and moving the balance wheel 
if the needle is already tight.
Maybe that paper ring inside the glass got weak, drooped down and held 
the needle as the balance wheel moved the pin under it.
You can't hurt it by trying it but be gentle with the speedo guts, 
needle and pin.
