Portugal 10, 20, and 50 Centavos, and 1 Escudo 1912 to 1916

Pretty coin, Melville. And made of silver, too:

10 CENTAVOS: 0.067 troy ounces silver
20 CENTAVOS: 0.134 ounces silver
50 CENTAVOS: 0.336 ounces
1 ESCUDO: 0.671 ounces

At a minimum, these coins are worth their Base Value (BV). That is, they are worth the value of the silver they contain. To figure BV, use the current price of silver (available from kitco.com) and multiply by the silver content. At this writing, silver trades at $20.15 US dollars per troy ounce, so the BV of a 50 centavos coin is 0.336 x 20.15 = $6.77. Tomorrow the price of silver will change, so be sure to look it up.

If your coin is not worn to a frazzle, it will be worth more than BV due to collector demand. Here are some typical catalog values:

10 CENTAVOS
worn: BV
average circulated: BV + $1
well preserved: BV + $2
fully uncirculated: BV + $6

20 CENTAVOS
worn: BV + $2
average circulated: BV + $25
well preserved: BV + $40
fully uncirculated: BV + $120
coins dated 1913 are worth a tad more than these figures
coins dated 1916 are worth a tad less than these figures

50 CENTAVOS
worn: BV + $2
average circulated: BV + $3
well preserved: BV + $5
fully uncirculated: BV + $20

1 ESCUDO
worn: BV + $3
average circulated: BV + $15
well preserved: BV + $40
fully uncirculated: BV + $70
