Nice find Trent! I hope it's the real deal! I just posted a video on my diamond ring find.... Very first one... Just shows not to stop digging those pennies as it was reading in the low 60's on my X-Terra Pro!
It's the real deal. Was super surprised at first as it rang up so high. I guess it was the base metal they mixed the gold with that used the higher tone.
That's an awesome find mate! I suggest getting 1lb of Jewellers shot, and pop it in the tumbler for 10-15 minutes! It will polish it like brand new!!👍🤟👊
