Cleaning silver beach finds

[berkshire mike]

Not much of a beach fan but after a pretty decent storm I figured why not give it a go. Plus I wanted to see how my ORX handled the salt. Tides weren’t in my favor so I wasn’t able to get very close to where the most significant erosion took place. Pretty much right away I was finding typical beach stuff, clad, pull tabs and modern trash. As time went on and the tide receded I was to get where I really to be. Started get some deep targets and soon was finding some older coins. Couple mercs, buffalo nickel and wheats. I also found a coin that I originally thought was a silver quarter but quickly realized it was too thin. This coin is pretty toasted but I can see a little detail and looking for advice on how I might clean it up enough to identify it.
Appreciate any help

Maybe 50 cent Queen Elizabeth II, Canadian?

Nice finds. Let us know what that coin is once you get an id.

Without an identified coin, you can file the edge a tiny bit and see what’s underneath it. Also I just rub it with moist salt really hard rub rub rub rub rub

I can sorta see a vague outline of this coin.

Do these dimensions seem right?

29.72mm (11.80 grams) 0.800 Silver
