Went to the local park again this morning for an hour with my son and we found some pulltabs and bits of cans, a washer, $2 coin, $1 coin and a football boot sprig.
My best attempt at a close up pic! They are just standard coins that are in circulation here but for my second find (other than pull tabs) EVER I am happy with them . Beginning to understand how the detector works so looking forward to finding more stuff at older parks.
