✅ SOLVED What is this penny and what is it worth?

1972-P Lincoln pulled out of a mint bag in the spring. But the PLANCHET is wrong. Seems to be made of brass. It's uncirculated. It is being tested and slabbed, so I should know I hope what it is on Saturday. Assuming it's a big mint mistake, IE a foreign planchet, what country do you think and how about a value?

It's a regular copper penny.
