Republic of China silver coin identification & valuation

Hi, I inherited a number of Republic of China silver coins, here are a sample of them. 

I wonder do these silver coins worth more than their metal value? thank you.

Welcome to Numista. Please, one coin at a time and provide as much information about each individual coin as possible. Individual photos of obverse and reverse in decent light. Weight, diameter, composition if known etc. They are not worth anything if not genuine and the only way to reasonably assess what you have exactly is with the information mentioned. The middle coin in the bottom row is not Chinese but Mexican.

I will need more information such as their weights to identify them better. There are many fake Chinese silver coins. I will just transliterate the words on the coins. 

#1 junk boat dollar year 8

#2 Chiang Kai-shek flying dragon commemorative

#3 Fat man dollar year 3 

#4 孙小头开国纪念币, likely year 1927 

#5 Mexican 8 Reales 

#6 British trade dollar 

They somehow look of to me, I fear that they might not be authentic.

To my mind all “coins” are fake. They looks like tourist tokens with a poor quality. I bet they cost a few dollars each.
