Two Dao Guang cash with large differences in size and weight [opgelost]

Is it a genuine coin ?

H#22.574 - East, large guang, radical of tong straight

brass yellow shiny, weight 3.8g (same as the Numista sheet)

Diameter only 22.8mm, (24mm reported in the Numista sheet)

and this following Boo-Yuwan looks a bit too large (diam: 25.0 mm), and too heavy weight: 4.62 g (vs 3.80 reported in the Numista sheet)

is it genuine?

Brass oxidized, large guang, 7 stroke bei, old furnace, 

H#22.594

with degenerated Yuwan ?

Consider the first one could be 22.578 (degenerate), and I would suggest 22.639 for the second one.

No doubt on authenticity
