Roman Coin Fakes?

[Jake G]

I bought the following coins from a large lot and from what I've come to learn about roman coins these don't feel authentic, minor details appear out of place, such as varying weights, abstract patinas and obscure writing, but i am far from knowledgeable and cannot tell if they are authentic or fake, can anyone say if they appear fake? Apologies for a pictures

Hi Jake,

Welcome to the discussion board!

I do not see anything suspicious from your photos?
It looks like a group of lower grade late roman coins with patinas of different colours and states of preservation.
Weights do vary from emperor to emperor, from type to type and coin to coin.
What do you mean by obscure writing? Legends on roman imperial coins are in Latin and often abbreviated.
Have a look at www.romancoin.info to get you started.

Thanks for your reply Peter,

With the writing a better way to explain it would be that there appears to be a 'top layer' to some of the coins that just seems to fall off in some cases, and for other coins if it touches anything like masking tape or even a light touch with a wooden tooth pick a blue-green powder like substance will just come off, is this normal?

It is normal for some poorly preserved, corroded coins.  It sounds like the coins suffer from active corrosion and will continue to deteriorate unless well-cleaned and neutralized.  In view of the apparent condition of many of these coins, that would be a labor of love rather than of economic advantage.

Certainly genuine.
