Thailand two coins from 1800's - Can anyone date them?

Can anyone provide dates for these two coins from Thailand (Siam)?


Thailand 1 Att - 1887-1905 - Bronze 24mm
The date on this one might be Bangkok Era 115 (1782+115=1897)


Thailand 1 Tical - 1876-1902 - Silver 31mm

Thank you.

Cant help you with the date, But there nice coins!!

 

I now believe that the silver Tical or Fuang coin might not have a date.

I looked on Ebay for "Thailand Silver" and found a couple of listings for the silver coin.
One listing was from a Thai seller, who indicated that the coin was "ND".
I figured that he would know how to read the date if it was there.

hya:

 

A date of RS 115 is a good guess on the first coin, I can't make it out any better from here. And yes, the second is not dated (1876-1900).
