Tried out my first detector today with results

[twinmaker2008]

I am New to the hobby, just recieved my new Tesoro tigershark in the mail and did not want to wait to go to the beach, so I went to the park down the street.
I found both of these coins in close proximity to each other. Can someone give me history on them, Also why is one silver 1935,and the 1937 looks copper. Are these worth anything?

Each buff is .750 copper and .250 nickel. However, each individual buff has its own personality I believe, based on ware & tare, age, location...Great finds, now "GET BACK TO THAT PARK"...there is more

Great start. I'm sure that park has many more surprises hiding, keep at it.

Great finds. The soil has been very kind to the Buffalo nickels. Mine come out all brown corroded.
