Santa Anna's spur?

Hi, this is an item that my parents brought home in the 1970s.  They said it was Santa Annas.  Back in the day they antiqued a lot and were knowledgeable in this regard.  I can not see them being gullible.  On a middle class income they were able to finance their "dream home" in the 1980s on the auction of many of their antiques.  Having said that, being an adult now, there does not seem to be a way to authenticate this claim.  This is why I am reaching out now to see if people who have knowledge in this regard can tell if could be true and answer if this has any value.

By mom and dads actions when they got home with this (I was young teen at the time) I know they spent some money on it.  Have no way of knowing.  Financially, could not see them paying a fortune but maybe up to a $1,000 back then would have been the limit I figure.  Most likely in the hundreds by the way they were acting.

In two days of research, it is definetely unique and pretty but beyond this, I do not know. 

If anyone can offer any thoughts on value of item and if they think it could have been Santa Annas it would be much appreciated.

Thanks.
