Spanish Colonial Coinage 8 Reales?

Yes I agree those 1808 Santiago 4R's are very ubiquitous realeswatcher and these are probably later. There are not many 4Rs of a CCC status or of a later period that are NOT Modern Forgeries. Beyond that 1808 Santiago mercuric silvering alloy variety (i.e, Never seen it as Sheffield silver plated only as Silver Mercuric Wash and confirmed by Material Analysis - owned about a DOZEN in my life all XRF verified - still own several). The 4R off-metal types seldom comes up to argue about as a CCC possibility or of a later period with most as 20thC Modern Forgeries. I mentioned this in Forgotten - Rarity increasing left to right in terms of denomination for Portraits in off-metal alloys in this pattern: 8R - 2R - 4R - then 1/2R and 1R (~ equally).
