Krypton or Kr (Superman's dog is named Krypto.) .
Molybdenum's electon configuration is [Kr] 5s1 4d5 this is because all elements want to be half-full or full. so the 2nd electron in the 5s2 moves to make the 4d4 complete so it turns to 5s1 4d5....making Mo half-full and stable.
It would depend heavily on the condition or grade of the coin just like any other coin . Prices and values will vary greatly so your best bet would be to see a reputable coin dealer but prices will be as little as melt value for extremely low grade or thousands for the higher top end grades. As I mentioned earlier - best to see a reputable coin dealer . Without actually seeing your coin it is hard to put a monetary value on it. I hope this helps you with your enquiry and wish you the best of luck in your search.

Look at the periodic table, do you see the 36 above the Kr? This is the atomic number. The atomic number represents the number of protons in an atom. This number is unique to each element a Kr atom will always have that number of protons.
36
t is Selinium, Se the third member of oxygen family
Kr and 36 protons
There are zero unpaired electrons in a krypton (Kr) atom because it has a completely filled electron shell with 8 electrons in the outermost energy level.
The atom of xenon (Xe) is larger than the atom of krypton (Kr) because xenon has more electrons and a larger atomic radius.
Kr has the atomic number of 36. It has similar number of electrons and protons.
This is the radioactive isotope bromine-78.
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
Strontium has 38 electrons. (Protons and electrons are the same)
There are 2 electrons in the highest occupied energy level of a neutral strontium atom, as the electron configuration of strontium is [Kr]5s^2.
This is the radioactive isotope bromine-78.
