Japan coin

Please corect me:
1 cash Yuan Feng T'ung Pao
2.92 g
24.89 mm
H-25.62
Japan imitation, bosen or 'mother coin'.




or this is the same coin like this:

This is a " BITASEN " Japan coin

Yes it is a H-25.62 but I don't think it is a seedcoin (which doesn't necessarily mean it isn't ), instead it is a high quality standard issue.
My reasoning: seedcoins have very smooth fields unlike the grainy fields like on regualar cash coins also the blank side of your coins is lacking the sharpness of a mothercoin.
Some examples in this video:

Seed coins are also bigger than the normal ones but you would need a second coin that is definitely not a seedcoin to compare (I looked around and found coins between 23,85 and 24,45 mm).
Nevertheless a great coin to have and maybe you could replace the current pictures of the nagasaki trade coins with yours.
