Anyone know about hand wrought nails?

pulled this hand wrought nail out of this table. Clearly really old. There’s probably 10+ types of nails in this table which seem to date to their respective repairs on the table. The legs don’t seem to be original to the rest of the piece. Anyone know about these nails? It’s about 5/8 of an inch

 

Looks like a horseshoe nail.

 

We are still on the topic of this table, are we not?

Help me date this old burled table please

 

Yeah. Anyone know any actual experts on primitive furniture/old growth lumber I can get in contact with?

 

here’s another, different nail. Definitely ain’t no 50 year old reproduction.

 

likely not........but u can't judge a table by it's nails only.
Many a carpenter has used whatever nails they had at hand..... and even old boards with nails already in place.
