Spanish 8 Reales Cut. Used For Where? Help!

Agree with other comments. Regular cuts let users of the coins know it is half weight,quarter weight. These irregular cuts, they do not seem practical for monetary use.

It is not impossible. But without documentation from the time about the use of such coins as money, and how they were cut, I will not believe the description of this as a north african standard. There are tons of records from these centuries in national archives. If this was used as money there will be records.

Heritage's best guess:

..............................WELL, DANG!.....LOOKIT' WHAT I FOUND IN MY "CUT SILVER BITT" COLLECTION......:

...I picked this up on ebay recently, in a lot, along with 2 cut copper Mexican colonial pieces ... It was cut from it's original weight (6.77g) to it's present weight: 3.939g ...

The angular cuts plus the reduction in weight, to 58% of it's original, coincides with these other Spanish coins (on this topic) suspected to have been trimmed to match Tripoli's coinage values, specifically, it's PARA issues ...

...anyone have any updated info in this topic?...

@jgen ...


...good question.

...there's a (small) market for clipped coins ... cutting coins for change was common in an era where coin shortage & lack of banks necessitated such a practice. This was common in the 1600s--early 1800s in areas, like North America, where many other countries' coins circulated freely ...

..the origin & explanation for these "North African" clipped coins & cobs are still unsubstantiated. No one has yet produced records substantiating this theory. It is, however, unusual that so many examples have surfaced, meeting the (supposed) criteria ...

...In the case of my single clipped 2 reales, it falls within the weight reduction parameter, is angularly cut ( especially the little end piece that was clipped, as if that was the final, small cut to achieve correct weight) ...see diagram ...

...I purchased this coin in a group of cut coins, not knowing about this subject, just happened to be in a group ...

Nice score, mrwiskers! I've bought coins from ufomechanix - a righteous seller. There was a thread a couple years ago in which someone was griping about the "commonly asked questions" on each of their auction pages, saying it raised red flags. Having sold on ebay, I perfectly understand why they have each of those there.

The Heritage commentary you shared highlights one of the more intriguing puzzles in colonial-era coinage. Spanish 8 Reales and 4 Reales—normally weighing 27.1 g and 13.55 g respectively—are often found clipped down to about 55-62% of their official weight. That leaves the 8 Reales at roughly 15-17 g and the 4 Reales at 7-8 g. The consistency of these reductions suggests a systematic practice rather than random damage or fraud.
What makes this especially interesting is the geographic context. Many examples have surfaced from hoards in Oran and Algeria, regions where Spanish silver was widely used but often adapted to local standards. The clipped weights align closely with the Tripoli 30 Para coinage of 1773, which weighed about 15-16 g. This suggests that local bankers or merchants may have cut Spanish silver to fit into a familiar weight system, effectively "converting" it into a locally acceptable denomination.
Another striking feature is the absence of counterstamps or standardized shapes. Unlike other regulated coinages where authorities marked or reshaped coins to certify their new value, these pieces appear to have been clipped in a more ad hoc but still consistent manner. That points to a makeshift regulatory system, likely carried out by local moneychangers rather than formal mints or governments.
Chronologically, most of these cut coins date to the 18th century or earlier, which fits the period of intense Mediterranean trade and piracy along the Barbary Coast. Spanish silver was the dominant international currency, but in regions with their own weight-based systems, adaptation was necessary. These cut-down reales may represent a hybrid monetary practice, bridging global bullion flows with local transactional needs.
For numismatists, they remain a fascinating riddle. Without documentary evidence of an official decree, we can't call them a sanctioned issue. Yet the consistency of the weights and their concentration in North African contexts strongly suggest intentional monetary adaptation. They sit at the crossroads of colonial coinage, Mediterranean trade, and localized economic improvisation.

...Well put, colonialjohn ... I've seen other examples of various nation's silver coinage, cut in similar fashion & sharing the same (rough) % of weight reduction...

...@jgenn ... by your request a specific gravity test, are you wondering if the coins are genuine or fake? ...Good point, & a good question,...

... damaging genuine coins for any other purpose would seem foolish, & producing fakes to promote a false narrative, also, seems foolish, as the cost would outweigh the effort ...

...Several knowledgeable cob dealers, including Sedwick (Dan), have noted & discussed the aforementioned possibility, using genuine cobs as examples...

...counterfeit cobs have been around since the 1st ones were struck...Anyone not familiar with these coins, not being to tell the difference, would share the same concerns as you ...

...also, the final determination of the validity of any coin should be done with the coin in hand, not by pictures ...

... in conclusion, (1.)I agree that anything of this type should be verified as genuine ... (2.) the hypothesis that these examples were an ad hoc adaptation is still just that: a theory ...

...a dang good theory with some intriguing evidence, that needs further investigation...

...anyone with similar examples, please post them here ...
