Well that's great, Bearcat. If you have a genuine 1884 10 centimos from the Philippines it is a valuable coin. As long as the stains and spots are not too bad, the 1884 date makes your coin valuable. That is a *good date* for this coin.
Spain minted 10 and 20 centimos for the Philippines with Alfonso's likeness on the front and the shield and crown pattern on the back from 1880 to 1885. Here are some typical catalog values for *common date* coins:
average circulated: $40
well preserved: $100
fully uncirculated: $2000
10 centimos dated 1885 are much more common and are worth about one-tenth of these values
coins dated 1880 are much more rare and are worth about 20 times these values
coins dated 1884 are more rare and are worth about 10 times these values
average circulated: $30
well preserved: $70
fully uncirculated: $300
20 centimos dated 1885 are much more common and are worth about one-third of these values
coins dated 1880 are more rare and are worth about 10 times these values
