Hi Peter --

The database I use has 548 Charles I crowns and half crowns from 1625, but I cannot find with the amazing, pronounce C R initials as your coin.

I will be happy to look further, but I need the detailed inscriptions (or at least partial inscriptions) from your coin, and I cannot read them from your pictures. Your pictures remain small and I can't enlarge them on my computer.

Please type out your best guess of the individual inscriptions.

Here's the issue. There are 1000s of half crowns of Charles I in the auction database I use to estimate approximate value. They all have honi soit etc. Many have CR and horseback king. I can't look through 1000s of pictures. I need inscriptions to separate out candidate coins.

Your pictures are small. I cannot read them accurately.

What are the two inscriptions above the CR? Are they XIII??? OVT:GIAS??? Is there ES or something between the CR??? Is there a date???

With that kind of info I can narrow the search to a few hundred coins. Once I find a match or two, the auction prices realized gives approximate value.

Ah. That did the trick, Peter.

As you say, it turns out it is a half crown weight, not an actual half crown. It carries the weight of a silver half crown.

Of the millions of coins in the CoinArchivesPro database, only one -- just one -- matches your piece. The one that match is from an old auction. The 3-weight set pictured below sold for $173 US dollars back in 2005. Yep, dollars were worth more back then. I'd wager your piece has risen in value to the $200 to $250 range, but that is just a guess.

Here is the auction description from Spink. The description is for the three weights shown.
