If it is made of fairly pure silver, it has what is called a scrap value. That is less than a melt value. 90% U.S. coins have a melt value and are traded as such. This has not real collector or investor following and only worth what it would be if it were melted and refined. If it is just a silver coating over base metal, it has almost no value.
And based on the different color of the metal where someone tried to scrape off the COPY stamp, it's not silver.
If it was produced after passage of the Hobby Protection Act in 1973, the COPY stamp is required by law, otherwise the producer could be charged with counterfeiting. This is regardless of the metallic content of the replica.
It is essentially worthless. It's the sort of thing you see in a "junk box" at a coin store. A dealer would pay little or nothing for this and be happy if he got 50 cents or a dollar for it.
