The bottom one has a better mintmark wheras the top one is worn down a lot.
This is off the top of my poor little head so I could be in error though.
Like he stated above they look like 1 real and 1/2 real coins hard to tell though for sure.
These types of coins were actually used a lot as money in the early USA, especially in the southern and western areas.
It's where the phrase "two bits, four bits, eight bits a dollar" comes from.
8 reals = one dollar
1 real = twenty cents
1/2 real = ten cents or a dime (disme)
there's a 2 real, a 1 real, and a couple of half reals.
