Some countries will do this when demonetizing their old currency and moving on to the new - and the N preceding a number is particularly seen with the Neuvo ("new") Pesos of both Uruguay and Mexico in the 1980s. (Thus, 5N would be 5 Neuvo Pesos).
When a country does this, the citizens will be given a period of time to cash their money in for the new currency, and after that time has expired, their "old" money no longer has spending value.
It mean the variable number, n, times five.

Mexico revalued its currency in 1992-93 due to hyperinflation. The N5 on your coin stands for "5 New Pesos". Note that Mexico uses the same $ sign as American dollars, but it represents pesos rather than dollars. The current exchange rate is roughly 10 pesos to the dollar, so your coin is worth about 50 cents U.S. Also, the coin is not silver and gold. The silver-colored part is stainless steel and the gold-colored part is aluminium-bronze. These are all inexpensive metals so your coin has no precious-metal value.
