New York Sidepath Tag

[bid4treasure]

Hoping to get some info on this sidepath tag. It is aluminum and about 2" long. I have tried all types of searches and can't seem to find any info. Is it known as something other than "sidepath tag"? Thanks in advance.

Well the auction for this tag is in a few hours and I was hoping to get some information. Since I can't find anything about it and have had no response here I am assuming it is insignificant and isn't something collectors desire?
