I need help identifying these coins

Weight Russian wire money in two last images. It narrows down period and you do not have a lot of identifiable information left on them.

It’s 4 grams

It’s 4 grams

this can't weight 4 metric grams. There are no coin holders that are that big, if we check how coin fits into holder in your photos.

Weight norms (denga = ½ kopeck, only two denominations were issued)

1505-1535 - 0.78 grams kopeck and 0.39 grams denga

1536-1608 - 0.68 grams kopeck, czardom starts here.

1608 - 0.64 grams

1613-1645 - 0.50 grams dropping down to 0.46

1646-1680 - 0.46-0.48 grams

1681 - 0.42 grams

1682-1696 - 0.40 grams

1698-1717 - 0.28 grams

You have offset stamp that tells only title (Czar and duke) without ruler's name. Other side is offset and heavily worn too. Without correct weight you got 1547-1717 year range.

Date and mint are written on coin holders of the two first chinese coins, you can find them in the catalog.

The last one is a japanese Kan'ei Tsūhō

It is just summary of data on old wire money website. 1608-1612 was time of civil war with mint standards not up to regular standard. It does not include gold variants discovered in 2015 digs and cooper variants
