BTD ideal weight and authenticity

Hi, need help from the experts with these 2 BTD which i have some doubts
Weighing 27.2 & 27.25
Magnet test is smooth
Ping sounds good

Any info greatly appreciated

Welcome to Numista. Photos of both sides of the coins would be the best way of helping to judge authenticity as well as providing other information such as diameter and thickness of each coin. The weight is a little concerning but could be explained by perhaps an inaccurate scale. "Ideal" weight is 26.9568g. Not sure what a smooth magnet test is either. On the surface of it, they don't look terrible but could be very good fakes.

​Excellent link and thread , very informative. His rims and milled edges look good which is a good sign in this case.
