I know DEAR, but I can not explain why only on the low relief? I just say maybe a DCAM or CAM business. I think this coin must be see in hand.

I think this coin must be see in hand. Well, that is one thing we can agree on..  If the mint had intentionally the devices frosts for a CAM or DCAM, then the roller lines could have been reduced by quite a bit. But I can barely see them on the profile. I cannot see them on the reverse device, but them the feathers and other details are quite possibly hiding them. |

If the planchet was rough, it may not remove these roller lines, even when they are struck twice. But the lines are at the same angle on both sides of the coin. So it is rolling lines.

That's definitely a proof coin. I am not aware that the US Mint made any cameo versions of a 1980 SBA in a business strike. I think the streaks may just be the haze that sometimes develops on these old proof coins, and maybe someone tried to wipe it off, or something on the original proof coin developed haze in that streaked way. I feel like I have seen that before. Perhaps a soak in acetone would remove the streaks if they are just haze? |

Thanks coop, I stand by my roller lines theory. But a nice soak in acetone might help.

Maybe the haze develops along the rolling lines.

I agree with Cointree. Just some hazing. Never seen roller lines on a proof. And as Silvio stated, proof planchets are specially polished.

So I went ahead and did an acetone dip, figured I don't have much to lose. Coin looks exactly the same as before the dip.
I'm almost certain it is a proof coin. Are there any lesser known qualities that may say otherwise?
Would you consider this a rare error?

Well, it IS a proof coin and I have never seen lines like this on aa proof (which I still think are roller lines.) is it rare? probably. is it an error? unlikely.
Maybe we call in Mike Diamond to view it.

If these are roller lines (and I have no alternative hypothesis), it's the first example I've seen in a proof. It's possible the planchet escaped the burnishing process. Alternatively, fine grooves might have been worn in the rollers, with these being transferred to the strip. If prominent enough, these lines could have survived the burnishing process.

Thank you very much Mike for your thoughts on this strange one.
