Need Help For Washington Quarter 1989 P Is It PMD Or Delam?

looks more like a clear glue that has yellowed over time.
I hope you didn't pay too much for it.

you can try a pure acetone bath over night to see if it soften up and can be removed..
Use 100% pure acetone from a hardware store - NOT fingernail polish remover, that has impurities in it and can ruin a good finish on a coin

@solo, I agree that this quarter is damaged rather than a mint error. I hope you can get your money back.

@Dearborn Thank you for your advice. i'll try the pure acetone. i'll post the result after the process is done.

I bought this about $ 0.35

@JimmyD, i'll soak it as your advice :D, thank you.

@Spence, I think better for me to let it go, it's only 35 cent anyway. Thank you Spence.

And thank you @Coinfrog.

i'll post the result after i'll soak it in pure acetone as @JimmyD and @Dearborn suggesting.

Have a good day all.
