As most of you know this is one of the three types of coins droped from dyna areas and campaign battles. They are use in VAST amounts by the wealthy or determined group of players that are making there relic weapon.
The coins needed for each stage are different but the layout is nearly all the same you need the small coins by the 100.
stage 1 - base weapon
stage 2 - base weapon +3 to +5 100's
stage 3 - Stage 2 weapon +14 to +16 100's
stage 4 - Stage 3 weapon + 59 to 61 100's
stage 5 - Stage 4 weapon +100 100's
This is not an easy task to do and there are rare ex items in there to get that can only be got in dyna areas that cant be sold or bazard. There are also used for upgradeing AF2-1 or relic armor in port jeuno 30 ish are needed per upgrade.
More specifically these little coins come from these specific Dynamis areas:
San d'Oria
Beaucedine
Xarcabard
Valkurm
Buburimu
Qufim
Tavnazia
However I'm not sure if it applies only to M Silverpieces or if they can both show up, but in certain campaign battles you can get them in those union spoils. I myself haven't had a chance to dive into campaign battles, so use Dynamis as a more reliable method to getting these and Silverpieces.
