Thanks so much for the response. I have also found bricks and nails that are from the Civil War in my yard. I recently bought a metal detector and that thing has been going CRAZY. I haven’t been able to dig yet but I’ve marked many spots where the bell was dug up. Will be digging soon. Thanks again!

Here's an earlier thread about WW2 US grenade pins.      And a web page selling MKII pin reproductions. https://ww2gear.shop/US-WW2-MKII-Grenade-Ring-Pin-Metal-Reproduction-p432268062

I bought this grenade pin from a military dealer because he claims it's WW2 and it looks real nice. Is this really a ww2 grenade fuze pin? Iv seen some pineapples with some green paint in splotches. I took the chance either way it wasn't much. Now I'm thinking is this a M67 vietnam pin? The patina looks old. People don't believe the pin i have is real so I'm looking to get a mint ww2 pin for a pineapple grenade just incase 30 years from now I regret not getting them. They are plentiful,  did I do good meaning its ww2 for a pineapple maybe m10a2? If it's a ww2 pin it's the best iv ever seen, so I took a chance. 

Thanks for posting! I’ll let yokota57 address this question since he’s the expert.

So is this a Studley restrike? 

Thanks Jerry much appreciated

Is that a PT-9?

That is possible or another private purchase "style"... here is an example belonging to VBF-1 pilot.  

Boom Stick! Groovy!   And the rest of your impression looks good to me too. mikie

What do you think about this Vietnam 'Coronet Rocky'? The insignia is skewed, the letters are wobbly, the case surface looks mint.
