PT and OT. What do they mean?

Recommended Posts

Being still fairly new to the hobby there are still many things I need to know. And some of them I'm sure are very basic.But without asking questions, I guess you never learn.

In my Spinks book it shows in the penny section abreviations such as

1854 OT DEF

1854 PT

1855 OT

Proof FDC

I have looked in the abreviation section of the book but can find nothing there to explain these.

Any suggestions would be helpful, both to me, and i am sure, many more newbies.

Many thanks.

OT and PT are 'ornamental trident' prongs and 'plain trident' prongs. Proof means a coin specially struck with polished dies and blanks and FDC, usually only used with proofs, standing for fleur-de-coin which essentially means the same as 'as struck' or as it left the mint.

And DEF: or DEF_: in Spink refer to the distance between the DEF the colon which follows.

The penny on the left shows a plain trident, while the coin on the right has an ornamental trident:

FDC is only used for coins with absolutely no blemishes of any kind (knocks, edge bumps, scratches, gouges, wear, imperfections). Understand that proofs are minted in a special way according to very exacting standards - only such coins are guaranteed blemish-free by a mint. Interestingly, FDC doesn't include toning, so a coin that's untoned, nicely toned, or ugly, can all still technically be described as FDC, so make sure you see a picture!

And just to throw a little confusion into the mix, the 1853 OT has an intermediate colon to DEF. Peck 1503 refers, but don't worry as it isn't very common.
